Abstract
An equalizer of a radio receiver for generating reliability information (q) that specifies probabilities of a received data symbol (z) being based on a particular transmitted value. The reliability information (q) is determined for each received data symbol (z) by evaluating trellis state transitions through use of a particular metric, both trellis-based symbols and decision-feedback symbols being evaluated. The decision-feedback symbols used are state-independent symbols that have previously been decided by means of a hard decision.
