ADAPTIVE NON-LINEAR MODEL FOR HIGHLY-SPECTRALLY-EFFICIENT COMMUNICATIONS

摘要

receiver is a non-linear model to be included in the sequence estimation processor used in the transmission symbols It is operable to produce the estimate of. Non-linear model may be adapted by the receiver based on a specific communication information that may indicate the non-linearity suffered are transmission symbols. The receiver may generate a reconstructed signal from the estimate of the transmitted symbol. Receiver can be adapted to non-linear model based on the values of the error signal generated from the reconstructed signal, the error signal value can be generated from a portion of the estimate generated, which may correspond to the known symbols and / or information symbols . The values of the error signal corresponding to the known symbol can be given a higher weighting factor in the adaptation algorithm, the values of the error signal for the corresponding to the information symbols is smaller weights in the adaptation algorithm can be given.
