Abstract

A multi-mode receiver and methods are provided, which use blind source separation (BSS) analysis to distinguish the various wireless communication signals from each other. Specifically, different signal types can be identified by BSS. The different signal types can be in overlapping frequencies or they can be in completely different frequencies. The BSS analysis may use center or carrier frequency, bandwidth, modulation scheme, access scheme, or wireless communication resources as an input to assist in the BSS.
