The performance of noncoherent M-ary frequency-shift keying (MFSK) with L branch signal-plus-noise (S+N) selection combining (SC) in two wave with diffuse power (TWDP) fading is studied. The fading on the diversity branches are assumed to be independent but not necessarily identically distributed. Two S+N SC receiver structures are examined and for each receiver a tractable bit error rate expression is derived. The effects of fading parameters on the relative performances of S+N SC and classical SC receivers are studied. Monte Carlo simulation results are presented to validate the obtained theoretical results.
