Patent ID: 8477892

Claim:
A communication receiver configured to receive a signal and provide improved synchronization, the receiver comprising: a plurality of primary filters, wherein the plurality of primary filters comprise a nominal primary filter and one or more additional primary filters each having a different combination of center frequency and bandwidth compared to the nominal primary filter, an antenna, operably coupled to an input of each of the plurality of primary filters, a plurality of signal decoders, each operably coupled to receive a filtered signal from a corresponding primary filter and output a corresponding recovered symbol signal and symbol error signal, a plurality of variable delay filters, each operably coupled between a primary filter and corresponding signal decoder, for delaying the corresponding filtered signal received by each of the plurality of signal decoders by a configured delay, a synchronization correlator, operably coupled to receive a filtered signal from at least one primary filter and output one of a timing, deviation, and frequency error signal, a multiplexer configured to output a selected lowest symbol error signal from among the plurality of symbol error signals output by the signal decoders, and a stochastic gradient algorithm processor, operably coupled to the output of the synchronization correlator and the output of the multiplexer, and operably coupled to an input of each of the plurality of variable delay filters, for setting a same delay at each variable delay filter as a function of (i) the one of the timing, deviation and frequency error signal and (ii) the selected lowest symbol error signal.
