ABSTRACT:
An equalizer is disclosed that compensates for non-linear effects resulting from a transmitter, a receiver, and/or a communication channel in a communication system. A non-linear decision feedback equalizer compensates for the non-linear effects impressed onto a received symbol by selecting between equalization coefficients based upon a previous received symbol. The received symbol may be represented in form of logic signals based on the binary number system. The two symbols most commonly chosen to represent the two logic values taken on by binary symbols are binary zero and binary one. When the previous received symbol is a binary zero, the non-linear decision feedback equalizer selects an equalization coefficient corresponding to binary zero to compensate for the non-linear effects impressed onto the received symbol. Likewise, when the previous received symbol is a binary one, the non-linear decision feedback equalizer selects an equalization coefficient corresponding to binary one to compensate for the non-linear effects impressed onto the received symbol.
