Performance of Fast Frequency-Hopped Noncoherent MFSK Conventional and Self-Normalization Receivers Over Rician- and Rayleigh-Faded Channel With Partial-Band Interference.

摘要

An error probability analysis is performed for an M-ARY orthogonal frequency shift keying (MFSK) receiver employing fast-frequency-hopped (FH) spread spectrum waveforms 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 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.
