Utility
Receiver with threshold level finder
9 May 23
An illustrative receiver includes: a decision element that derives symbol decisions from a slicer input signal; an equalizer that converts a receive signal into the slicer input signal; a summer that combines the symbol decisions with the slicer input signal to produce an error signal; and a level finder that operates on said signals to determine thresholds at which each signal has a given probability of exceeding the threshold.

Utility
Power-efficient nonlinear equalizers and methods
20 Sep 22
One illustrative equalizer converts a receive signal into a sequence of symbol decisions using: a linear filter that filters the receive signal as part of deriving a first sequence of equalized signal samples; a first decision element that derives a tentative sequence of symbol decisions from the first sequence of equalized signal samples; a nonlinear filter that, when enabled, applies nonlinear compensation to the linearly filtered receive signal as part of deriving a second sequence of equalized signal samples; a second decision element that, when enabled, derives replacement symbol decisions from the second sequence of equalized signal samples; a subtraction element that calculates an equalization error for each symbol decision in the tentative sequence; and a controller that selectively enables the nonlinear filter and the second decision element to obtain a replacement symbol decision for each symbol decision in the tentative sequence having an equalization error greater than a predetermined value.
