Embodiments are disclosed for equalizing a pulse amplitude modulation signal for a receiver in a communication system. An example method includes receiving an electronic signal. The electronic signal encodes a plurality of symbols in a number of amplitude levels in a plurality of pulses in the electronic signal. The example method further includes estimating multiple symbol values using all possible values of an immediately preceding symbol for each symbol in the electronic signal. Each estimated symbol value is determined using one of the possible values of the immediately preceding symbol. The example method further includes receiving an actual value of the immediately preceding symbol and selecting an actual estimated symbol value from the multiple symbol values based on the actual value of the immediately preceding symbol. The actual estimated symbol value may be used as the actual value for selecting an estimated symbol value of an immediately subsequent symbol.
