Performance analysis of coherently detected FFH/BPSK with maximal ratio combining receiver over Rayleigh fading channel with multitone jamming and imperfect channel estimation

Fast frequency hopping (FFH) system is an effective method to combat jamming in military applications. In FFH system over fading channels, noncoherent detected frequency shift keying (FSK) is commonly used. In this paper, we derived the error performance of a FFH system based on coherently detected binary phase shift keying (BPSK) over Rayleigh fading channel. The jamming type is assumed to be multitone jamming (MTJ). The channel estimation is assumed to be affected by additive while Gaussian noise (AWGN) and MTJ.
