Abstract
In described examples of a signal equalizer, a complex signal having a first signal component and a second signal component is received from a communication channel. Adaptive equalization of crosstalk between the first signal component and the second signal component is performed using a single complex tap of a feedforward equalizer. A feedforward filter with real only taps converts the channel into a minimum phase channel that has postcursor interference only so that a low complexity decision feedback filter with all complex taps can easily eliminate the postcursor interreference.
