The power line communication (PLC) channel is mainly affected by noise that is either caused by appliances or induced into channel from external source. The effects of those noises on transmission network constitute major problem that must be tackled. In this paper, a time domain noise measurement and characterization is presented. A design measurement system was set up that captured the noise in time domain for real indoor power line communication. Noise samples were captured with four channel digital storage oscilloscope (DSO) GDS-1052-U with two inputs channels. The time domain noise measurement is presented together with its statistical analysis based on numerous measurement campaigns in different laboratories at Afe Babalola University Ado Ekiti Nigeria, within three months; October, November and early December 2019. The measurement was taken between the hours of 8am-6pm, Monday-Saturday. Those days were equally distributed over three months of investigation. The measurement was carried out when all the electrical loads were running. The parameters of the noise measurements in terms of its duration, amplitude, impulsive and background noise voltage were examined. We compare our results to that of literatures; in comparison, the disparity with respect to durations and amplitude (mean and standard deviation) is quite significant.

ABSTRACT The aim of this paper is to develop a complete model of a power-line communication (PLC) system operating on a medium-voltage (MV) network. The core-shield configuration was chosen for signal transmission in the power cables. In order to validate the developed model experimental, the medium-voltage network of the Favignana island was used to carry out detailed testing. The transmission was performed between two transformer substations in the presence of mains voltage (i.e., 24 kV). ST7540 FSK power-line transceivers, together with capacitive coupling interfaces, were used for the transmission and the reception of the communication signal. The correlation between the experimental measurements and the simulation results would appear to validate the use of the developed model for the analysis of MV transmission channels.

Access technologies for data transmission, such as xDSL, Wi-Fi and cable modem are widely used once they support high data transmission rates at low cost. Among these technologies, Power Line Communications (PLC) is an alternative promising solution. In order to get control over a telecommunication network operation, including PLC, it is necessary to use management techniques. Besides network control, these management techniques are intended to provide maximum knowledge of the system behavior and of involved devices. In this paper, we present a management solution model applied to PLC networks. In order to develop the proposed management system for PLC networks, we made use of a free software called Nagios. Practical evaluation tests showed that the proposed management model is scalable, reliable and can provide effective control of PLC networks in order to guarantee the required services to the users.

The rapid advances in home and building automation technology impose the fact of reliable communication systems and devices that control electronic equipment. A considerable issue of controlling such equipment will efficiently manage the energy in order to save more of the exploited electricity. Lately, the National Institute of Standards and Technology issued processing standards to direct the researcher’s attention to Power Line communication (PLC) which is considered as one of the most important schemes of communications over AC power line. Several methods of communication over a power line have been proposed and realized such as X-10 and CE bus and applied very profitably to help in energy management for both customer and utility. In this paper, Power Line Modem (PLM-1) and Smart Meter methods are proposed and presented as to provide a reliable communication and allows designing more cost-effective PLC transceivers to serve managing energy at home and elsewhere.

Permutation coding (PC) has been known to be effective in combating power line channel impairments, when used in concatenation with other channel coding schemes like
convolutional or Reed Solomon (RS) codes, using FSK, PSK or
DPSK as the modulator. We hereby report the development of
a modified DPSK modulator, called differential quinary PSK
(DQuiPSK), with only 5 constellations, to improve the performance of permutation coded DPSK-OFDM modulation for power line communication (PLC) purposes. This combination is, therefore, termed an RS-PC-DQuiPSK-OFDM scheme, with RS being used as an outer code. To implement this over power line, universal software radio peripherals, which are software defined radio hardware, originally designed for radio communications, were used together with narrowband coupling circuits, to interface with the power line. Simulations and practical implementation results show the strength and competitive performance of our scheme over the conventional convolutional coded D8PSK-OFDM scheme specified in the narrowband PLC standard.

LED (Light Emitting Diode) lamps have recently come on to the market as energy efficient alternatives to incandescent light bulbs. Although energy effective, they inject conductive noise into the power-line system. This can have a detrimental effect on the power-line communications channel. This paper investigates these effects when LED lamps are seen as noise sources on the power line. It shows that there are two classes of LED lamps - depending on the noise generating electronics used as drivers for the light emitting diodes. Different driver electronics have different influences in different parts of the emission spectrum. It is shown that in the CENELEC band: (3kHz-150kHz) the interference level from LED lamps is significantly below the allowed maximum PLC signal levels. In the band 150kHz-30MHz however, PLC signals compete with Electromagnetic Compatibility (EMC) levels and the SNR can be equal to zero, but only if the lamps have active power electronic converters

Communication over existing electrical wiring has attracted many researchers as a last mile solution due its reduced cost of installation. To make this medium as a feasible alternative to other communication medium, it is important to evaluate the performance of indoor electrical wiring. In this paper, an attempt is made to analyze and compare the various types of power line channel modeling techniques. The importance of modeling the cable parameters is also discussed. A sample residential power line network is considered and the channel frequency response and the channel capacity are compared for the various channel modeling techniques.

Power lines that carry communication signals tend to produce radiated electromagnetic interference (EMI). In this paper it is shown how this, usually negative effect, is used for contactless signal transmission. Commercial PLC modems operating in the 150kHz - 30MHz band are used and LAN signals are contactlessly transmitted and received up to 2m.

Power Line Communication (PLC) is the use of the existing public and private mains power wiring for the transmission of telecommunication signals (data). PLC technology is used for a variety of functions, such as computer networking, utility control systems and smart grid. However, one of the predominant challenges faced by PLC is noise, often provoked by end-user equipment. In this paper, an algorithm to characterize different noise types-peculiar to PLC-is developed. Twelve devices across three load classes (residential, commercial and industrial) are chosen for the study. Experimental measurements are carried out on the devices to capture signals of interest. The characterization process in the work is a combined approach of the Power Spectral Density (PSD) and time stream. PSD analysis is carried out on the captured noise signals using the Welch's PSD estimation technique. The PSD and other parameters obtained from the time stream are used for the characterization process. Major findings show that most of the devices exhibited either colored background noise, periodic impulsive noise synchronous with the mains or periodic impulsive noise asynchronous with the mains. The outcome of this research will be useful for development and deployment of power line technologies in a manner that mitigates noise problems.

The scope for broadband power line Communication is considered as a retrofit technology for wide geographical coverage wherever the human habitation exists. So during the last decade, it has drawn an enormous quantity of research work for improving communication performance and this system being standardized all over the world. The broadband power line Communication channel modelling is essential in the design of a reliable communications system. An analysis on the proposed channel model is conducted in this paper; also the paper studied the noises in Broadband powerline Communication network and its
mathematical model. The channel Transfer function and Error Performance of Proposed power line communication System noise is evaluated with various digital modulation techniques Bit error rate (BER)
and signal to noise ratio (SNR) curve by using simulation software. The results indicated that the noise analysis is effective for modelling the power line communication channel. Also, we have presented the
various studies on the channel performance based on Orthogonal frequency-division Multiplexing (OFDM) systems for an efficient design of a Broadband Power line Communication (BPLC) system.

— Though the concepts of MIMO technique is not new in the field of wireless communication, the potential of this technique is yet to be fully evaluated in the field of power line communication. In this paper one such attempt is made by comparing the Channel capacity of a MIMO power line channel with SISO power line channels of the same electrical network. To accomplish this task, a 3-wire indoor power line network is considered with multiple distributed branches. The transfer function of the power line channel is modeled using the concept of multi-conductor transmission line theory and the electromagnetic interference in the power line is modeled using the Middleton Class A noise model. To analyze the electromagnetic interference in the channel, a conducted emissions test (CE 102) is performed on the power line network.
