Abstract

We analyze the error performance for the noncoherent reception of M-ary orthogonal frequency shift keying with postdetection equal gain combining (EGC) over a correlated fading channel. Two kinds of correlated fading statistics are considered: (1) Nakagami fading in which the diversity branches can have different m-parameters, (2) Rician fading in which the in-phase component of the complex channel gain of any branch can be correlated with the quadrature components of the gains of all other branches. Using the characteristic function of the combiner output signal-to-noise-ratio, closed-form expressions for the symbol error probability are obtained
