摘要

本文提出了一种对抗编码时分多址(TDMA)系统中多址干扰的有害影响的方法。最优异步多用户检测器适用于TDMA系统，该系统具有单个期望用户和少量强干扰操作在具有相同扩展码的相邻小区中的特点。提出的接收机具有软输入/软输出(SISO)多用户检测器和SISO信道解码器，操作在迭代反馈或“涡轮”配置中。仿真结果显示了两个用户(期望用户和一个强干扰者)的联合检测，每个用户使用一个弱递归系统卷积码。

Combined multiuser reception and channel decoding for TDMA cellular systems

This paper presents a method of combating the detrimental effects of multiple-access interference present in coded time division multiple access (TDMA) systems. The optimal asynchronous multiuser detector is adapted for use by TDMA systems, which are characterized by a single desired user and a small number of strong interferers operating in adjacent cells with identical spreading codes. The proposed receiver features a soft-input/soft-output (SISO) multiuser detector and a SISO channel decoder operating in an iterative feedback, or "turbo" configuration. Simulation results are shown for the case when two users, the desired user and one strong interferer, are jointly detected and each user employs a weak recursive systematic convolutional code.
