In this paper, we analyze the effect of interference diversity on the capacity of a cellular system that employs frequency hopping (FH) and bit-interleaved coded modulation (BICM). Interference is created when the hopping patterns of adjacent cells intersect with the patterns of the cell of interest, with a probability that depends on the occupancy of each cell. However, due to frequency hopping and power control, the power of the interference varies across the received symbols creating what is usually named in the literature as interference diversity. The performance of two receivers is studied; a receiver that tracks the variations of the interference power across the received symbols and a receiver that remains oblivious to these variations. The combined effects of fading, propagation loss, shadowing and power control are taken into account. Our analysis aims at demonstrating, under what circumstances, the additional complexity of tracking the interference power variations is justified.
