Abstract

Capacity limits and throughput results are evaluated for slow frequency-hop transmission over channels in which the bandwidth of the partial-band noise may vary but the total power in the noise is constant. The system employs orthogonal modulation, noncoherent demodulation, and error-control coding with iterative decoding. We find that the capacity limits for the system and the performance results for turbo product codes and low-density parity-check codes show that the throughput can be a nonmonotonic function of the bandwidth of the partial-band noise. We discuss how such nonmonotonicity affects the design of adaptive-rate coding systems.
