This paper presents a computer simulation based study of the tracking behavior of a decision-feedback equalizer coupled to a carrier-recovery loop in the presence of dynamic multipath fading activity. Free interaction between the two adaptive devices is allowed. 16, 64 and 256 QAM modulation schemes have been analyzed. Minimum phase <-> Non minimum phase type fading transitions are studied since they are highly constraining events for the system performance. Comparative results considering baud and fractionally spaced equalizers are presented.
