Adaptive coding technique employing concatenated Reed Solomon and convolutional codes

An adaptive coding scheme employing concatenated Reed Solomon codes and convolutional codes has been proposed. This scheme employs the information available from the channel state estimator to vary the amount of redundancy and its error correcting capability according the state of the channel. Simulations have been carried in AWGN and slow Rayleigh fading channels and the results show that the adaptive concatenated scheme gives significant amount of improvement over the concatenated scheme.
