Patent ID: 7190308

Claim:
A communications device for separating source signals provided by M signal sources, the communications device comprising: an antenna array comprising N elements for forming at least N antenna beams for receiving at least N different summations of the M source signals, with N and M being greater than 2; a controller connected to said antenna array for selectively forming the at least N antenna beams; a receiver assembly connected to said antenna array for receiving the at least N different summations of the M source signals; and a blind signal separation processor connected to said receiver assembly for forming a mixing matrix comprising up to the at least N different summations of the M source signals, said blind signal separation processor also determining if the different summations of the M source signals are correlated or statistically independent, and if not, then cooperating with said controller for forming different beans for receiving new different summations of the M source signals to replace the different summations of the M source signals that are not correlated or statistically independent in the mixing matrix, and separating desired source signals from the mixing matrix.
