Blind signal separation using spreading codes |
摘要 |
A communications device for separating source signals provided by M signal sources includes an antenna array comprising N antenna elements for receiving at least N different summations of the M source signals. A code despreader is connected to the N antenna elements for decoding the at least N different summations of the M source signals. Each one of the N different summations includes k codes for providing k different summations of the M source signals associated therewith. A blind signal separation processor forms a mixing matrix comprising at least kN different summations of the M source signals, and separates desired source signals from the mixing matrix. The mixing matrix has a rank equal up to kN. |
