Patent ID: 8213553

Claim:
In a system receiving a composite signal comprising a desired signal having desired data and an interference signal having interfering data having a plurality of frames, a method of identifying the interference signal, comprising the steps of: (a) demodulating the composite signal to produce the desired data; (b) remodulating the desired data to generate a reconstructed desired signal; (c) subtracting the reconstructed desired signal from an at least partially demodulated composite signal to generate the interference signal; (d) at least partially demodulating the interference signal using a first scrambling code of a plurality of scrambling codes to produce a first demodulated interference signal; (e) computing a histogram of a frame synchronization statistic of the first demodulated interference signal; (f) repeating steps (d) through (e) to produce additional demodulated interference signals to form a plurality of demodulated interference signals that includes the first demodulated interference signal and to generate a plurality of histograms of the frame synchronization statistics, one histogram for each of the plurality of scrambling codes; and (g) identifying the interference signal as one of the plurality of demodulated interference signals associated with the histogram having the lowest variance of the plurality of histograms.
