Abstract:
1. A detector for a receiver; said detector generating a clock phase detection signal and a carrier phase detection signal from of a plurality of clock polyphase signals of an oversampled signal; said detector comprising: a plurality of carrier phase detectors, each determining the carrier phase of an applied clock polyphase signal of said plurality of clock polyphase signals and each emitting a carrier phase signal corresponding to said respective carrier phase; a plurality of variance estimation units, each determining the variance of one of said carrier phase signals; a selection unit which compares the variances of said carrier phase signals with one another and emits a selection signal as said clock phase detection signal for selection of that clock polyphase signal whose associated carrier phase has the smallest variance; and an output unit which emits at least one of said carrier phase signals as said carrier phase detection signal.
