Abstract
A receiver and method for the same are provided. In the receiver, a decoder may decode an equalized signal to generate symbol decisions and a soft information signal. An equalizer may select boundary levels for non-uniform quantization using a soft information signal delayed by a symbol interval. The equalized signal may be generated from a feedback-filtered signal using the symbol decisions.
