Non-linear equalizer in communication receiver devices

Disclosed are methods, systems, devices, apparatus, media, design structures, and other implementations, including a method is that includes receiving, at a receiver device, a signal transmitted from a remote wireless device, with the signal including a training sequence, and updating, based on the training sequence, one or more adjustable characteristics for a non-linear equalizer of the receiver device, with the one or more adjustable characteristics controlling signal non-linear compensation processing to correct non-linear distortions affecting communication signals transmitted from the remote wireless device. In some embodiments, the method may further include updating, based on the training sequence, additional one or more adjustable characteristics for a linear equalizer of the receiver device, with the additional one or more adjustable characteristics controlling signal linear compensation processing to correct linear distortions affecting the communication signals.
