Alternative protocols are presented for adapting the code from packet to packet in a mobile, wireless, ad hoc network that employs frequency hopping, coherent or noncoherent demodulation, and soft-decision decoding on channels with time-varying propagation loss and time-varying partial-band interference. The protocols can be employed with a wide range of codes and decoding algorithms. No channel measurements...
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...
