Performance of dual MRC over non-identical TWDP fading channels

Performance expressions of Dual maximal ratio combining (MRC) receiver are derived for the receiver over non-identical two wave diffused power (TWDP) fading channels are derived. The probability density function (PDF) of the receiver output signal-to-noise ratio (SNR) is derived using characteristics function of the output SNR expression. The derived PDF expression is then used to obtained the various performance measures such as outage probability and average symbol error rate for both coherent and non-coherent modulation schemes. Studies on the effects of fading parameters (K and Δ) and modulation techniques on the performance of the diversity system are carried out. The numerically evaluated results are validated with either Monte Carlo simulation or published results.
