Ｍ＝４正交信号时数字通信系统进行蒙特卡罗仿真程序，当均值分别等于０，０.１，１.０，２．０时完成１００００个比特的仿真并求出误比特概率。绘出理论误码率和蒙特拉罗仿真的差错率并进行比较这俩个结果，并绘出每个均值情况下判决器的１０００个接受信噪比抽样(M = 4 orthogonal signals in digital communication systems Monte Carlo simulation program, when the mean, respectively, equivalent to 10,000 completed 0,0.1,1.0,2.0 simulation bit and bit error probability are obtained. Mapping theory and蒙特拉罗BER simulation这俩error rate and compare results, and the mean circumstances of each mapped)

说明：  增广路的程序 挺简单的 大家看说明就能看懂 (widen the road quite a simple procedure you can understand looking)

本设计通过利用VB 编写用户操作界面和MATLAB 实现后台运算及图形处理的混合编 程的方法，来完成对通信原理仿真系统的开发。设计中采用ActiveX 技术来实现VB 和MATLAB 之间的通信，在VB 应用程序内创建MATLAB ActiveX 对象，实现对MATLAB 的调用，最终 仿真实现信源编码解码、模拟调制解调、数字基带传输、数字调制解调等功能。(This design user interface written using VB and MATLAB computing and graphics processing to achieve the background of mixed programming method, to complete the simulation system for the development of communication theory. Design using ActiveX technology to achieve communication between VB and MATLAB, the VB application, create a MATLAB ActiveX object, call the MATLAB implementation, to achieve the ultimate source codec simulation, analog modem, digital baseband transmission, digital modulation and demodulation functions.)

说明：  基于matlab的QPSK调制及其误码率曲线(QPSK modulation and the bit error rate curve)
