Abstract:	We present the performance analysis of a fast frequency-hopped (FR) binary orthogonal frequency-shift keying acquisition receiver for communication against adverse environments, The receiver employs noncoherent, noise-normalized, matched-filtered (in) correlation detection for rapid acquisition in the search mode, Our analysis includes four types of communication environments, namely additive white Gaussian noise (AWGN) channel, AWGN channel with partial-band noise jamming, fading channels, and fading channels with partial-band noise jamming, The considered fading channels include Nakagami-m, Rician, and Rayleigh amplitude models, Based on Beaulieu's convergent series approach [1], efficient analytical formulas are developed for performance evaluation, Example performance results for various environments are presented in terms of two acquisition probabilities, namely the detection probability and the false alarm probability of the noise-normalized MF detector, It is analytically shown that with a short MF correlation length and with a sufficiently targe ratio of signal power to noise power the fast FH diversity combining yields noticeable performance improvement for environments with strong fading, When the MF correlation is lengthened, this improvement tends to fade away and the diversity combining results in performance loss.
