本文针对并行干扰抵消检测器的不足之处,提出了改进的并行干扰抵消检测算法——基于多项式展开的并行干扰抵消多用户检测算法。该算法将多项式展开检测器作为并行干扰抵消检测器第一级的数据估计值,以提高检测可靠性。通过仿真实验,首先验证了多项式展开检测器的性能。然后比较改进算法与传统检测器的性能,验证改进算法的系统性能得到明显改善;并与并行干扰抵消检测器、解相关检测器和MMSE检测器相比较,验
证得到该改进算法的性能也有不同程度的改善。
(this paper discusses the principle and performance of the
conventional detector and the parallel interference cancellation(PIC)detector
separately.Since the conventional detector take MAI only as the background noise without considering the existence of the other users,the existence of MAI has a significant impact on the performance of CDMA systems.Each stage of PIC detector utilizes the data estimates of the initial or previous stage,produces a new set of MAI estimates,and then subtracts out all of the MAI for each user in parallel.Through Monte Carlo simulation in different scenarios,the results illustrate the influence of MAI in conventional CDMA ystems.Theexperimental results show PIC detector can effectively eliminate MAI andimprove the system BER.

现代数值分析(MATLAB版)-马昌凤
说明: 本教材各章节的主要算法都给出了 MATLAB 通用程序。为了更好地配合本书的教学,书后编写了一个附录,简明扼要地介绍了数学软件 MATLAB 的入门知识和必要的程序设计和绘图等基本技能技巧。个人感觉很实用,推荐给大家!(The main algorithms in each chapter of this textbook give MATLAB general procedures. In order to better match the teaching of this book, an appendix is written after the book, which briefly introduces the introductory knowledge of the mathematical software MATLAB and the necessary basic skills such as programming and drawing. Personally feel very practical, recommended to everyone!)
