Time-based decision feedback equalizer

Abstract:

In some examples, a time-based equalizer can be configured to receive an input signal from a channel. The input signal can be distorted by previously received input signals transmitted over the channel. The time-based equalizer can be configured to compensate for distortions in the input signal caused by at least one previously received input signal to provide an ISI compensated input signal. The time-based equalizer can be configured to compensate for the distortions by edge time shifting respective edges of the input signal in time over a time interval for detecting the input signal to new edge time locations based on a feedback signal and edge movement signals. The feedback signal can be generated based on at least one previously received input signal.
