  • cdma多用户检测算法的仿真
    matlab 程序,包括3个文件:mseries.m编写了一个产生m序列的函数;mud.m用来比较传统单用户检测、线性解相关多用户检测、最小均方误差多用户检测的误码率;mud_plot比较后并画出误码率-信噪比曲线。

  • C#项目源码100例
    【实例简介】这里有本人搜集的C#源码100例,其中都是小项目,对使用Visual Studio中的常用工具有很好的促进作用,个人觉得只要能把其中的一部分真正吃透就能够打下比较好的基础了。而且通过练习我也发现,模仿源码项目并真正靠自己的理解写出源码是最好的学习方式之一,现在把这些源码例子拿出来和大家分享一下,希望对您有所启发!

  • 基于matlab灰色模型GM(1,1)预测数据
    基于matlab灰色模型GM(1,1)预测数据,通过对已知数据进行处理,预测出新的数据,然后对比其结果,求出误差,已经对结果进行后验差检验,从而来判断预测准确性。
