    • 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.
    • 公开了一种用于执行由其他人不共享的联合随机性(JRNSO)的方法和装置。 在一个实施例中,使用基带信号环回和专用导频在频分双工(FDD)中确定JRNSO。 在另一个实施例中,使用基带信号环回以及专用导频的组合,专用增益函数和卡尔曼滤波定向处理,在时分双工(TDD)中确定JRNSO。 在一个示例中,FDD和TDD JRSNO实施例在单输入单输出(SISO)和单输入多输出(SIMO)通信中执行。 在其他示例中,FDD和TDD实施例在多输入多输出(MIMO)和多输入单输出(MISO)通信中执行。 通过减少与SISO或SIMO通信的MIMO和MISO通信来确定JRNSO。 JRNSO也使用MIMO信道产品的决定因素来决定。 通过利用矩阵产品的对称属性来消除通道限制。

    • A spread spectrum communications system includes an antenna array for receiving different summations of desired and undesired signals, and receivers are coupled to the antenna array. Each receiver operates based upon a respective channel code for de-spreading the desired and undesired signals for determining at least one desired signal associated with the respective channel code, and for combining the at least one desired signal and the undesired signals after the de-spreading. A processor is coupled to the receivers for forming a mixing matrix based upon the combined signals from each receiver, with entries on a diagonal of the mixing matrix corresponding to the desired signals and entries adjacent the diagonal corresponding to the undesired signals. The processor also processes the mixing matrix so that a level of the desired signals increases and a level of the undesired signals decreases. A demodulator is coupled to the processor for demodulating at least one desired signal.
