multiuser
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.

C-Progrmming-Language(second)
本书是由c语言的设计者brian w. kernighan和dennis m. ritchie编写的一部介绍标准c语言及其程序设计方法的权威性经典著作。全面、系统地讲述了c语言的各个特性及程序设计的基本方法，包括基本概念、类型和表达式、控制流、函数与程序结构、指针与数组、结构、输入与输出、unix系统接口、标准库等内容。
本书的讲述深入浅出，配合典型例证，通俗易懂，实用性强，适合作为大专院校计算机专业或非计算机专业的c语言教材，也可以作为从事计算机相关软硬件开发的技术人员的参考书。 在计算机发展的历史上，没有哪一种程序设计语言像c语言这样应用如此广泛(C language book is written by the designers of brian w. kernighan and dennis m. ritchie write a description of the standard c language and the authority of the program design classic. Comprehensive and systematic about the c language of all the basic features and programming methods, including basic concepts, types and expressions, control flow, function and program structure, pointers and arrays, structures, input and output, unix system interface, the standard library and so on.
Book about simple terms, with a typical example, user-friendly, practical, suitable as a computer professional or computer professional colleges of the c language materials can also be as engaged in computer-related hardware and software technology developed by staff reference. In the history of computer development, no programming language such as c language so widely used)
