摘要： Interference cancellation is implemented for a multiple antenna system. The multiple antenna receiver is provided that includes a whitening filter coupled to receive processed signals corresponding to signals received at respective antennas, and to generate whitened signals corresponding to each of the received signals, having a colored noise component whitened. The whitening filter coupled to determine the whitened signals, at least in part, utilizes symbols corresponding to the signals received by the plurality of antennas. A signal separator is coupled to supply the whitening filter with processed received signals having interference components reduced as compared to received signals.

摘要： A Transmit Diversity Redundancy controller (210) dynamically mediates implementation of diversity and antenna hopping by detecting and remediating faults on antenna branches (220) while minimizing the capital investment required. The controller monitors the equipment along the antenna branches. If a fault occurs, the controller determines the appropriate fault remediation measures to implement based on default settings, or relays an indicator to an external processor (e.g., a BTS or BSC CPU) and awaits instructions. If traffic on the BTS in high, the external processor instructs the TDR controller to combine the signals carried by the downed branch with the signals carried by the active branches, and the combined carrier signals are transmitted over the active branches. Otherwise, the external processor instructs the controller to allow signals carried by the downed antenna branch to be dropped, and notifies the BSC to suspend assignment of calls to the dropped carriers until the branch is restored.
摘要翻译：发射分集冗余控制器（210）通过在天线分支（220）上检测和补救故障来动态地调节分集和天线跳频的实现，同时最小化所需的资本投资。控制器监视沿着天线分支的设备。如果发生故障，则控制器根据默认设置确定要实施的适当的故障修复措施，或将指示器中继到外部处理器（例如，BTS或BSC CPU）并等待指令。如果BTS上的业务处于高电平状态，则外部处理器指示TDR控制器将被分支的分支所携带的信号与有源分支所携带的信号进行组合，组合的载波信号通过主动分支传输。否则，外部处理器指示控制器允许由降频的天线分支携带的信号被丢弃，并且通知BSC暂停对丢弃的载波的分配，直到分支被恢复为止。
