Description: 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.

Description: 盲多用户检测的LMS和RLS算法,在DS/CDMA通信系统中，为了解调出用户的有用信息，必须尽可能地抑制由其它用户扩频信号产生的多址干扰（MAI，Multiple Access Interference）。尽管最佳多用户检测器可以很好地抑制MAI，但其运算量会随着用户数的增加而呈指数增加。盲多用户检测技术可以在不知道其他用户信息的情况下检测出目标用户，所以在实际应用中有着十分重要的应用前景.-LMS and RLS algorithm Blind Multiuser Detection in DS/CDMA communication system, in order to demodulate the user useful information, must be possible to inhibit the spread spectrum signals generated by other users multiple access interference (MAI Multiple Access Interference) . Although the optimal multi-user detector can suppress MAI, but its computational complexity increases exponentially with the number of users increase. Blind Multiuser Detection technology can not know the other user information detected the target user, has a very important application prospect in practical applications.
