基于Matlab语言的现代通信仿真分析,仿真实现了主要模块二进制信息源输入，16QAM调制，发射滤波器，接收滤波器，采样，均衡，信号检测，16QAM解调，信息还原输出，产生BER曲线图。

采样率转换程序，程序主体分为上采样与下采样-Sample rate conversion process, the program is divided into the main sampling and down-sampling

经典的二阶矩四阶矩信噪比估计，有不经过上采样、成型滤波和经过上采样、成型滤波的两种版本。加噪方式也分别用了matlab自带函数和自写两种版本。望大家参考。-Second Moment classic SNR estimation fourth moment, there is not through the sampling, the shaping filter and sampled, two versions of shaping filter. Plus noise mode were

低通采样 用MATLAB设计低通,带通,高通和带阻FIR数字滤波器()
