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:

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.
