SQL+Prompt+v5.3+v6.1
本人在Windows7 64位 SQL Server 2012环境下测试通过(系统是全新安装)使用方法：1，安装SQLPrompt v5.3.0.3，这个不多说。2，安装完毕后，断开网络连接。3，打开Visual Studio或者SQL Server Management Studio(版本不限)。4，在菜单栏找到SQL Prompt5，点击，找到Serial Number/Enter Serial Number...5，启动SQLPrompt Keygen 5.3.x，注意在右侧选择Edition下来列表为：Professional。6，复制SQLPrompt Keygen 5.3.x显示的序列号，粘贴到刚才弹出的对话框中，点击Activate，因为是断网的，系统会要求离线激活。7，然后在新弹出的对话框中，将右侧那一堆代码复制出来，粘贴到注册机的上面框中，这时注册机会在下面的框中生成新的注册激活代码。8，复制粘贴生成的激活代码，到Enter Serial Number...弹出激活框的右侧，点击激活，然后OK。

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.
