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 are needed, and no external side information is supplied to the receiver. Performance results are provided for packet transmissions that employ turbo product codes. The protocol performance results are compared with capacity limits and with the performance for hypothetical ideal protocols that use perfect channel-state information to select the codes that maximize the expected throughput.
