A receiver includes a filter for filtering a received signal to produce a
filtered signal. A converter 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 and a restorative signal that compensates for the ISI. A
detector detects symbols in the baseband signal to produce a decision
signal. A restorative signal generator generates, from the decision
signal, the restorative signal responsive to the frequency-offset
estimate, such that the restorative signal compensates for the ISI.
