Abstract
In this work various channel equalization algorithms operating in the frequency domain are described in a unifying framework. First, minimum mean square error linear and decision-feedback equalizers are derived and a synthesis technique based on the well-known Levinson-Durbin algorithm is proposed for the latter. Then, iterative linear and decision feedback equalization algorithms for turbo processing are devised. Performance results for both uncoded and coded PSK transmissions show the efficacy of the proposed equalization techniques and their superiority over other existing frequency domain equalization strategies.
