Energy harvesting techniques and performance analysis for L-MRC receiver in Rayleigh fading channels
Tóm tắt
In this paper, we have presented the performance of a wireless receiver with an energy harvesting technique. The conventional employ for multiple receiver antenna degrades the impact of wireless fading in a communication channel. In this work, we have introduce the energy harvesting system to split the received RF signal into two streams with a power splitter (PS) factor with adjustable power levels. The expressions of our system consider arbitrary channel parameters and diversity branches. The probability density function of the overall received SNR has been derived, and the performance analysis like outage probability (OP) and average bit error rate (ABER) for a different modulation schemes are presented to evaluate its performance. The effects of system parameters, such as power splitter ratio and diversity order of Rayleigh fading channels, are studied. The analytical results are corroborated with the help of Monte-Carlo simulation and found to be close. The proposed system will be helpful when we require reliable data transmission in an energy-limited scenario.
