    • A method and apparatus are provided for separating signals from a received combined signal in a wireless communication system. Combined signals are received by one or more antennas, demodulated and filtered. The combined signals are mixed with known scrambling codes of a target sector and possibly interfering sectors prior to signal separation, by which a separation matrix is created. The separation matrix is used to provide separate desired and interferer signals, such that the desired signals may be despread with known spreading codes for further decoder processing. In an alternate embodiment, the separation matrix is split according to scrambling and spreading code processing to decrease processing complexity. Feedback adjustment control may be used to adjust separation parameters based on generated separation matrices and separated signals.
    • 提供了一种用于在无线通信系统中从接收到的组合信号中分离信号的方法和装置。 组合信号由一个或多个天线接收,被解调和滤波。 组合的信号与目标扇区的已知扰码相混合,并且可能在信号分离之前与干扰扇区混合,由此产生分离矩阵。 分离矩阵用于提供单独的期望信号和干扰信号,使得所需信号可以用已知的扩展码进行解扩,用于进一步的解码器处理。 在替代实施例中,根据加扰和扩展码处理分离分离矩阵以降低处理复杂度。 可以使用反馈调整控制来基于产生的分离矩阵和分离的信号来调整分离参数。

    • A communications device for separating source signals provided by M signal sources includes an antenna array comprising N antenna elements for generating N initial antenna patterns for receiving N different summations of the M source signals, with N being less than M. The antenna array includes an elevation controller for selectively changing an elevation of at least one of the N initial antenna patterns for generating at least one additional antenna pattern so that at least one additional different summation of the M source signals is received thereby. A blind signal separation processor forms a mixing matrix comprising the N different summations of the M source signals, and the at least one additional different summation of the M source signals. The mixing matrix has a rank equal to N plus the number of additional different summations of the M source signals received using the additional antenna patterns. The blind signal separation processor separates desired source signals from the mixing matrix.
