Abstract :
A new JSCCM scheme based on multi-layer feed-forward network is proposed. The coding and modulation of traditional system is replaced by a neural network. At the receive end, a network maps the deteriorated modulation signals to reconstructed signals, the demodulation and decoding of the traditional system is replaced. Simulation results show that the performance of the neural networks is superior to the traditional system. The result is a useful basis for applying neural networks to transmitter and receiver of communication system.
