We evaluate the capacity of the reverse link of a synchronous FH/SSMA multi-cell network in the presence of partial band jamming. A set of orthogonal frequency hopping (FH) patterns is assigned to the users in each cell. Cells are differentiated by concatenating the user FH pattern with a shuffling sequences of the same hop rate. The use of guard times enables synchronous operation for the range of hopping rates of interest. The capacities of the above FH/SSMA network with either coherent BPSK modulation or non-coherent BFSK modulation are first evaluated for the AWGN channel. The effect of power control errors on the system performance is accounted for in each case. Then the effects of Rayleigh fading are factored in. Similar results for asynchronous DS/SS cellular network (reverse link) are also reported for comparison purpose.
