| 摘 要： | 将粗糙集(RoughSet)与多用户检测相结合,提出一种新型的多用户检测算法。粗糙集可以在期望用户的特征波形、定时、时延和多径等信息未知时,对接收数据进行约简,提取出接收数据与期望用户符号之间的规则,从而进行有效的分类,可以较好地应用于复杂的信道环境。理论分析和仿真结果表明了该方法的有效性和实用性。

| Abstract: | A new rough set-based method for multi-user detection is presented. Firstly, rough sets can reduce the received data and induct rules between the received data and the symbols of the interested user when the signature wave, timing, delay and multipath of the interested user are unknown, then give a effective a classification using inducted rules. The properties of the method make it suitable for many complicated channel environments. Simulation results and theory analysis show that the method is effective and practical. |
