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. )

ubuntu系统性能优化简单教程 关闭最小化动画 长期使用 Ubuntu 后有一种感觉，那就是在 GNOME 中启动应用程序时，速度越来越慢。在 Ubuntu 英文论坛那边看到一个技巧，可以对这个问题起到改善作用。打开 /etc/hosts 文件，可以看到类似下面的内容： 。。。。。。。。。。。。(Ubuntu system performance optimization simple tutorial Close minimize animation After long-term use of Ubuntu, it is a kind of feeling in the GNOME started in the application, the more and more slow. In English BBS there see a Ubuntu on this problem technique that can play improved. Open/etc/hosts file, can see similar the following content: )

C开发人员，初级面试100道题，可以多看看，有利于打开开发的门。(C developers, primary interview 100 questions, you can see more, to open the doors of development.)

Qt，和 wxWidget 一样，它也是一个标准的 C++库。但是它的语法很类似于 Java 的 Swing，十分清晰，而 且 SIGNAL/SLOT 机制使得程序看起来很明白——这也是我首先选 择 Qt 的一个很重要的方面，因为我是学 Java 出身的 :) 。不过，所谓“成也萧何，败也萧 何”，这种机制虽然很清楚，但是它所带来的后果是你需要使用 Qt 的 qmake 对程序进行预 处理，才能够再使用 make 或者 nmake 进行编译。并且它的界面也不是原生风格的，尽管 Qt 使用 style 机制十分巧妙的模拟了本地界面。另外值得一提的是，Qt 不仅仅运行在桌面环境 中，Qt 已经被 Nokia 收购，它现在已经会成为 Symbian 系列的主要界面技术——Qt 是能够 运行于嵌入式平台的。(Qt, and wxWidget, it is also a standard C++ library. But its syntax is very similar to Java' s Swing, very clear, and SIGNAL/SLOT mechanism makes the program seem to understand- and this is my first choice is a very important aspect of Qt, because I was born to learn Java :). However, the so-called " as also Xiao, also lost" , although this mechanism is clear, but its consequences is that you need to use Qt' s qmake program is preprocessed, it can be reused make or nmake to compile. And its interface is not the native style, despite the use of Qt style very clever mechanism to simulate the local interface. Also worth mentioning is that, Qt only run in the desktop environment, Qt has been acquired by Nokia, it has now become the main interface technology Qt Symbian series is the ability to run on embedded platforms.)
