This paper presents the comparative study of rectangular shaped microstrip patch textile antenna for different conductive textile materials and conductive non-textile materials. The textile antenna is designed, evaluated using ADS 2013.06 software and measured by N9926A 14 GHz field fox handheld vector network analyser for the industrial, scientific and medical (ISM) band application operated at the resonant frequency of 2.4-2.485 GHz. These textile antennas are analysed and compared by the performance parameters like VSWR, reflection coefficient, bandwidth, impedance, directivity and gain. The results of the proposed design shows the return loss of −53.32 dB, the VSWR as 1 and 100% efficiency, narrow bandwidth, effective directional radiation pattern, 50 ohm impedance, highest gain and directivity of about 5 dB and 5 dBi.

Coding plays a major role in achieving the target. LDPC codes are being the desired ones in achieving reduced area and power input. This paper presents a high performance error detection and correction for non-binary low density parity check codes (LDPC). Check node processing is formulated by using Euclidean graph decoding architecture. The proposed decoding method reduces the number of iterations and achieves reduction in area and power.

Orthogonal Frequency Division Multiplexing (OFDM) has become a promising technique for high data rate wireless communication systems. It has been widely employed for 4G systems like WiFi, DVB - T, WiMAX, LTE - A etc. Here LTE physical layer downlink is considered which conveys information from enhanced base station (eNodeB) to mobile user equipment (UE) using Orthogonal Frequency Division Multiple Access technique for LTE physical layer downlink channel estimation. To overcome the disadvantages of existing channel estimation methods, a new method is proposed by combining LS and MMSE methods using Genetic Operators like Mutation and Crossover. In this method, a four step algorithm is used. The best channel estimation matrix is selected with minimum error among the three estimated matrices with the help of fitness function. The simulation results show the performance of the new proposed method with BPSK is better and produces low NMSE ranging from 10-15 to 10-3 and zero BER. With more number of iterations, QPSK is better than BPSK in proposed method but has higher BER than BPSK. The selection of modulation schemes in adaptive modulation is essential. This technique can be used in medical field for transferring patient information immediately to doctor and can be used in situations where the ambulance cannot be arrived in time to the accident or wounded area.

A novel design of a Microstrip Patch in Ultra wideband is proposed for microwave imaging in biomedical applications. Antenna is a key component for detection of abnormality in biological signals. The proposed structure is compared with conventional structure in terms of antenna parameters in wide range of frequency band. Performance analysis of the designed antenna is evaluated in terms of return loss, input impedance, fractional bandwidth, radiation pattern, and antenna efficiency. Breast cancer detection with mammography basically utilizes a low dose X-ray as the initial diagnostic tool. Frequent exposures to X-rays of any kind are really not recommended for young people.
