Abstract :
The performance of noncoherent M-ary frequency-shift keying (MFSK) with dual-branch postdetection switch and stay combining (SSC) in two-wave with diffuse power (TWDP) fading is studied. A closed-form expression for the average bit error rate (BER) of noncoherent MFSK with dual-branch postdetection SSC is derived. Monte Carlo simulation results are presented to verify the validity of the obtained analytical expressions. The effects of TWDP fading parameters on the relative performances of postdetection and predetection SSC receivers are studied. It is shown that postdetection SSC has superior performance over predetection SSC.
