Abstract: A method and apparatus for communicating radio frequency signals that may reduce the susceptibility of the signals to jamming. A digital voice signal may be interleaved and transmitted with error correction signals related to the voice signal. The transmission may use frequency hopping with each hop including appropriate synchronization signals, data signals and error correction signals. The received signal at the receiver portion of the signal may contain means for removing both nonexcisable and excisable interference. The nonexcisable interference may be identified and removed by (1) assuming different jamming patterns, (2) decoding to resolve the received signals for each of the assumed jamming patterns, and (3) voting all of the resolved signals to determine which assumed jamming pattern produces the best results. An adaptive filter for removing excisable jamming may applied when such jamming is detected.
