The design and performance of a neural network for predicting turbo decoding error with application to hybrid ARQ protocols.

The design and performance of a neural network for predicting turbo decoding error with application to hybrid ARQ protocols.

It is shown that a neural network can be trained to observe the cross entropy of the outputs of component decoders in a turbo error control system and to accurately predict the presence of errors in the decoded data. The neural network can be used as a trigger for retransmission requests at either t...
