Patent ID: 6985545

Claim:
A wireless communication receiver for processing a superposed RF (radio frequency) signal containing two or more RF signals occupying overlapping RF bandwidth, the wireless communication receiver comprising: a wideband receiver for receiving said superposed RF signal; an analog to digital converter for converting said received superposed RF signal to a superposed digital signal using a common digitizing rate; a channelizer for each of said RF signals that receives said superposed digital signal and limits said superposed digital signal to a bandwidth that corresponds with the bandwidth of each of said RF signals, providing a bandwidth clipped digital signal for each of said RF signals; and a signal handling device for each of said RF signals that receives one said bandwidth clipped digital signal, said signal handling device comprising: a multi-user detection decoder that shares data with multi-user detection decoders in other ones of said signal handling device to decode said bandwidth clipped digital signal to remove conventional and multi-access interference and provide a decoded digital signal; and a rate adjuster that adjusts a sampling rate of said decoded digital signal to provide an output signal having a predetermined sampling rate.
