说明：  matlab课程大作业，共两个小程序，一个是根据shouming.txt 中的数据分析人均寿命分布情况；另一个是任意输入两个相向而行的波的幅度、频率、相位，观察这两个波叠加的动画，比如可以形成驻波、拍等典型的波(matlab course great job, a total of two small programs, one is based on shouming.txt life expectancy in the distribution of data analysis the other is the two meet each other halfway arbitrary input wave amplitude, frequency, phase, observation of these two waves superposition of the animation, such as to form a standing wave, making the typical wave)

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)
