Performance analysis of FFH/BFSK using division combining receiver in GPS system
Li Deng, Kaijun Xu, Qin Wang, Jingzhou Sun · 2016
In this paper, we consider a new kind of nonlinear combing receiver of FFH/BFSK mode in GPS system. in the effects of partial-band noise jamming over additive white Gaussian noise channel and frequency-nonselective slowly fading channel. The diversity is performed using multiple hops per data bit. It was shown that the GPS system using division combing receiver has better performance under the strong interference or strong fading than the system without diversity when signal to jamming ratio is relatively low.
