Performance of a L-MRC Receiver over Equally Correlated η-μ Fading Channels

Performance of an L branch maximal ratio combining (MRC) receiver has been analyzed in equally correlated η-μ fading channels. For the combiner output signal-to-noise ratio, analytical expressions for the probability density function, moments and outage probability have been obtained. For the MRC receiver, expressions for the average bit error probability for binary, coherent and non-coherent modulations have been presented. Numerical results have been plotted to illustrate the effect of fading correlation and diversity order (L) on the receiver performance. Both numerical and Monte Carlo simulation results have been found to be closely matching.
