摘要/Abstract

摘要：

提出了一种适用于消除蜂窝移动通信系统在频率选择性衰落信道的共道干扰(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的最佳接收机的性能．

关键词: 共道干扰, 单天线干扰消除, 软入软出, 迭代接收机

Abstract:

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-output (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.

Key words: co-channel interference, single antenna interference cancellation, soft-input soft-output, iterative receiver
