Patent ID: 8374564

Claim:
A method of obtaining a signal of interest from a plurality of signals of interest comprised in a composite signal: receiving a composite signal containing an interfering signal and a plurality of signals of interest; centering a replica of the interfering signal relative to the composite signal by frequency translating the replica of the interfering signal using a complex rotator; reducing the composite signal to at least the bandwidth of a desired one of the plurality of signals of interest using a downlink bandwidth filter to form a filtered composite signal comprising the desired one of the plurality of signals of interest and a remaining portion of the interfering signal within the bandwidth of the desired one of the plurality of signals of interest; reducing the bandwidth of the replica of the interfering signal to at least the bandwidth of the desired one of the plurality of signals of interest using an uplink bandwidth filter to form a filtered replica of the interfering signal; and canceling the remaining portion of the interfering signal using the filtered replica of the interfering signal to produce the desired one of the plurality of signals of interest.
