Performance Analysis of Rayleigh Fading Channel using the Hybrid Technique- MRC/EGC

Hima Pradeep V, Seema Padmarajan

Fading is the most important issue for Wireless Communication .To remove adverse effect of fading in wireless channels a well-known scheme used is diversity combining technique. Transmitted signal is received through multiple numbers of independent fading paths in diversity receiver. These signals are combined to improve the signalto- noise ratio (SNR) of the received signal. A new hybrid diversity scheme MRC/EGC for Rayleigh fading channel in which M number of branches carry out maximal ratio combining and L number of branches carry out equal gain combining is proposed in this paper. The effectiveness of this hybrid diversity scheme is evaluated by analysing the performance of the system in terms of Outage Probability and Average Bit Error Rate (ABER).
