Performance evaluation of noncoherent frequency-hopped spread-spectrum cellular radio networks over fading channels

The authors characterize multiple-access for cellular mobile radio networks, in which users are assumed to be Poisson-distributed in the plane. These networks use frequency-hopped or hybrid direct-sequence/slow frequency-hopped spread-spectrum signaling. The Gaussian approximation technique is used to compute the symbol error probability for both types of spread-spectrum signaling with noncoherent MFSK modulation, and for a general class of dispersive fading channels. Numerical evaluations of an example of a doubly dispersive fading channel are presented.<
