ABSTRACT:
A method for operating a communications device for separating an independent source signal from a mixture of source signals provided by M signal sources includes receiving at an antenna array at least M different summations of the M source signals. The at least M different summations define the mixture of source signals, where N<M. A signal separation processor processes the mixture of source signals by taking samples of the mixture of source signals over time and storing each sample as a data vector to create a data set, and assigning each data vector within the data set to one class within a plurality of classes based on its similarity to other data vectors in the one class. The data vectors assigned to the one class are analyzed to separate the independent source signal from other signals in the mixture of source signals.
