Split FTDNN-DFE Equalizer for Complex Non-linear Wireless Channels with NARMA Approximation
Journal of Intelligent Systems, 2017 Time-dependent channel variations in wireless systems have been modeled using autoregressive (AR), moving average, and AR moving average (ARMA) approaches, which in certain conditions fail to provide the most suitable description of the scenarios.
