摘　　要：提出了一种用于消除频率选择性衰落信道共道干扰(CCI)的单天线干扰消除(SAIC)接收机.该接收机采用并行结构,对每路共道信号分别做软入软出(SISO)检测,利用检测器输出的软信息和译码提供的外信息做迭代干扰消除,其复杂度仅随共道信号数目线性增长.仿真结果表明,该方案可以逼近无共道干扰时最佳接收机的性能.A single antenna interference cancellation （SAIC） receiver was proposed for suppressing the co-channel interference （CCI） of cellular mobile communications system in frequency selective fading channels. The receiver with parallel structure detects each co-channel signal with a soft-input soft-out- put （SISO） detector separately. The soft information provided by the detectors and the decoders is used as the a priori information for the iterative cancellation of CCI. Its complexity only grows linearly with the number of co-channel signals. Simulation shows that the performance of the proposed scheme converges to that of the optimal receiver.
