As error probability analysis is performed for an M-ary orthogonal frequency shift keying (MFSK) receiver employing fast frequency-hopped (FH) spread spectrum waveform transmitted over a fading channel with partial-band interference. The partial-band interference is modeled as a Gaussian process. Wideband thermal noise is also included in the analysis. Diversity is performed using multiple hops per data bit. Each diversity reception is assumed to fade independently according to a nonselective Rician process. A nonlinear combination procedure referred to as self-normalization combining is employed by the receiver to minimize partial-band interference effects.
