An error probability analysis is performed for a noncoherent M-aryorthogonal frequency-shift keying (MFSK) communication system employingfast frequency-hopped (FFH) spread spectrum. The signal is assumed to betransmitted through a frequency-nonselective, slowly fading channel with partial-band interference. The partial-band interference is modeled as a Gaussian process.The noise-normalized receiver is employed to minimize partial-band interference effects, and the effect of inaccurate noise measurement on the ability of the noise-normalized receiver to reject partial-band interference is examined. Each diversity reception is assumed to fade independently according to a Ricean process.Thermal noise is also included in the analysis. It is found that diversitydramatically reduces the degradation due to partial-band interference, and noisemeasurement error does not significantly degrade receiver performance. The robustness of the receiver with regard to noise measurement error is independent of the strength of channel fading.
