ADAPTIVE DEMODULATION METHOD AND APPARATUS USING AN ARTIFICIAL NEURAL NETWORK TO IMPROVE DATA RECOVERY IN HIGH SPEED CHANNELS

摘要

A neural network demodulator is used within a receiver to provide Inter Symbol Interference (ISI) channel equalization and to correct for I/Q/phase imbalance. The neural network is trained with a single integrated training step to simultaneously handle the channel impairments of ISI equalization and I/Q phase imbalance as opposed to prior art methods of separately addressing each channel impairment in sequence.
