An error coding for satellite channels with interference

The authors discuss the results of an investigation into improved error correction coding for satellite channels experiencing adjacent and cochannel interference, which constitute a nonstationary, non-Gaussian noise environment. The codes under study are those achieved by concatenation of a convolutional code and a Reed-Solomon code. Test results in the Gaussian channel showed geometrical error-length probability mass functions from a convolutional decoder. In the interference channel, test results showed a bimodal error-length mass function. It is shown that the amount of burst errors in either the geometrical or bimodal functions is proportional to the ratio of noise power density in the receiver and the receiver´s phase-lock loop, respectively.<>
