Patent ID: 7113129

Claim:
A communications device for separating source signals provided by M signal sources, the communications device comprising: an antenna array comprising N antenna elements for receiving at least N different summations of the M source signals, with N and M being greater than 1, said N antenna elements comprising at least one antenna element for receiving at least one of the N different summations of the M source signals, and at least two correlated antenna elements for receiving at least two of the N different summations of the M source signals; said at least two correlated antenna elements being uncorrelated with said at least one antenna element; a receiver 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 for forming a mixing matrix comprising the at least N different summations of the M source signals, the mixing matrix having a rank equal up to at least N, said blind signal separation processor for separating desired source signals from the mixing matrix.
