The Generalized Delayed Decision Feedback Sequence Detector (GDDFSD) is a scheme for detecting uncoded data corrupted by ISI and noise.The GDDFSD is a variant of the DDFSD, the variant being that in the GDDFSD multiple survivors are allowed for each state.In the paper, it is proposed to adopt as a front-end the mean-square whitened matched filter in place of the classical whitened matched filter.Simulation results show that our proposed design gives substantial benefits when a severe frequency selective channel is considered.
