Generally,the aviation communication system has some constraints,such as power,bandwidth and latency.To satisfy its requirements of high coding gain and low latency to channel coding,the paper derives the theoretical Shannon limit on the minimum SNR required for coded system,especially for the binary communication system.And then,the performance of several typical kinds of channel coding is analyzed through simulation.Finally,qualitative analysis is made to the application scope of the different channel coding methods with consideration of the technical indicators of them.The conclusion has engineering significance for the selection of channel coding in aviation communication systems.
