ABSTRACT:
A symbol clock recovery subsystem uses a tap delay line having a set of delays, uses a clock bank of samplers providing time-staggered sampled noncoherently received signals, and uses a set of mean magnitude generators, in channelized form, for providing a set of mean magnitudes to a maximum selector for selecting a maximum one of the time-staggered sampled received signals having the greatest signal to noise ratio so as to provide a signal effectively occurring at symbol epoch time for demodulating a symbol stream in a digital communication system receiver.
