Therefore, the understand of antenna characteristics, which effects on waveform distortion, is necessary. This paper presents the waveform distortion due to human body for wireless meadical applications based on measurement data. The template waveform is considered at the receiver side to maximize the SNR for evaluation. In this results are evaluate based on the extended Friis' transmission formula. This technique gives very accurate results and is very useful for the design and evaluation of UWB-BAN transmission waveform for wireless medical applications, especially focusing on the effect of template waveform.

Research paper thumbnail of Evaluation of SFN gain for DVB-T2

2017 International Conference on Digital Arts, Media and Technology (ICDAMT), 2017

The evaluation of power gain and modulation error ratio (MER) gain of Digital Video Broadcasting ... more The evaluation of power gain and modulation error ratio (MER) gain of Digital Video Broadcasting - Second Generation Terrestrial (DVB-T2) for Single Frequency Network (SFN) is very important for the performance of the receiver. The power gain and MER gain are considered based on the data measurement. However, the quality of service in the SFN area will depend on the number and nature of the received signal (number of transmitters, relative delays, and relative amplitudes). In this paper, we proposed to estimate the reception quality under the SFN environment with the delay spread of two transmitters no longer than the guard interval. The results are useful for estimation and analysis the DVB-T2 Single Frequency Network performance and optimization for DVB-T2 network.

The SFN mode also increases the concentration of the signal in overlap areas. However, some different of overlap areas in actual use of SFN networks may have some degradation of the received signal due to the effect of the SFN. In this research, we analyze SFN broadcasting in SISO mode. This paper represents the effects of delays on the SFN signal over different delay times within the guard interval by analyzing the minimum reception threshold. The analysis of received signal power, MER, bBER, LBER, and noise margin are studied using an actual digital television transmitter for the experiment. The results show that the minimum thresholds for a delay time at 0 microseconds will require higher receive signal power than other delay times within the GI. The results of this experiment are useful in des...
