Patent ID: 7231227

Claim:
A method for processing a wireless communication signal, the method comprising the steps of: receiving a combined wireless communication signal, the combined wireless communication signal having at least two component wireless communication signals, the component wireless communication signals differing from each other in at least one of the following ways: having different center or carrier frequencies, having different bandwidths, having different modulation schemes, having different access schemes, and having different wireless communication resources; splitting the received signal into a first branched signal and a second branched signal; converting the combined wireless communication signal to a combined base band signal by mixing the first branched signal with a first carrier frequency signal and mixing the second branched signal with a second carrier frequency signal, the first and second carrier frequency signals having center or carrier frequencies indicative of the at least two component wireless communication signals; performing blind source separation (BSS) analysis based on the converted base band signal; and outputting at least two different base band signals representing the at least two component wireless communication signals.
