    摘要: A communications system includes multiple mobile wireless communications devices transmitting at a same time to a fixed receiver assembly. Each mobile wireless communications device transmits a source signal defined by a respective character set comprising a plurality of symbols. At least one of the symbols in the respective character sets is transmitted at a different power level so that the transmitted source signal from each mobile wireless communications device appears with linearly independent power level time periods. The linearly independent power level time periods are used by the fixed receiver assembly to populate a mixing matrix for signal separation processing.

    摘要: A method and apparatus for performing Joint Randomness Not Shared by Others (JRNSO) is disclosed. In one embodiment, JRNSO is determined in Frequency Division Duplex (FDD) using a baseband signal loop back and private pilots. In another embodiment, JRNSO is determined in Time Division Duplex (TDD) using a baseband signal loop back and combinations of private pilots, private gain functions and Kalman filtering directional processing. In one example, the FDD and TDD JRSNO embodiments are performed in Single-Input-Single-Output (SISO) and Single-Input-Multiple-Output (SIMO) communications. In other examples, the FDD and TDD embodiments are performed in Multiple-Input-Multiple-Output (MIMO) and Multiple-Input-Single-Output (MISO) communications. JRNSO is determined by reducing MIMO and MISO communications to SISO or SIMO communications. JRNSO is also determined using determinants of MIMO channel products. Channel restrictions are removed by exploiting symmetric properties of matrix products.

    摘要: A communications device for separating source signals provided by M signal sources includes 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 is connected to the antenna array for selectively forming the at least N antenna beams. A blind signal separation processor forms a mixing matrix comprising up to the at least N different summations of the M source signals. The blind signal separation processor also determines if the different summations of the M source signals are correlated or statistically independent, and if not, then cooperates with the controller for forming different beams 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. The desired source signals are separated from the mixing matrix by the blind signal separation processor.

    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.
