Patent ID: 7295601

Claim:
An apparatus comprising: an antenna; a front end receiving a signal spectrum from said antenna; an A/D converter coupled to said frontend and digitizing said received signal spectrum; a digital baseband processor in communication with said A/D converter and extracting and demodulating a plurality of individual channels from the digitized signal spectrum; and an optimum sampling phase selection circuit receiving one of said individual channels and determining an optimum sampling phase from said one of said individual channels, the optimum phase selection circuit comprising: a demultiplexor receiving an oversampled digital baseband signal at an input and providing a plurality of downsampled phases at respective outputs; a correlation detector receiving said plurality of downsampled phases and providing a respective phase to a respective correlation peak detector, said correlation peak detector providing a peak sum signal for each downsampled phase; a maximum detect circuit receiving said peak sum signal for each downsampled phase from said correlation detector and providing an optimum phase output signal; and a multiplexor receiving said plurality of downsampled phases and receiving said optimum phase output signal from said maximum detect circuit, said multiplexor providing one of said downsampled phases as an optimum phase at an output such that symbol timing is determined based on the relative offset peaks in said optimum phase.
