RECEIVER HAVING DECISIONAL FEEDBACK EQUALIZER WITH REMODULATION AND RELATED METHODS

摘要

A receiver includes a filter (106) for filtering a received signal to produce a filtered signal. A converter (120, 126) converts the filtered signal to a baseband signal that is substantially free of an initial frequency offset and inter-symbol interference (ISI), responsive to a frequency-offset estimate (122) and a restorative signal (608) that compensates for the ISI. A detector (140) detects symbols in the baseband signal to produce a decision signal. A restorative signal generator (606) generates, from the decision signal, the restorative signal responsive to the frequency-offset estimate, such that the restorative signal compensates for the ISI.
