产生64QAM基带通信系统发射机：基带成型滤波采用3种方式

1）采用每个符号调制一个成型滤波函数，然后将各个函数进行时域叠加的方法；

2）采用信号与低通滤波器响应函数卷积的方法；

3） matlab自带的升余弦函数

English Description：

Generation of 64QAM baseband communication system transmitter: baseband shaping filter adopts three ways
1) Each symbol is used to modulate a shaping filter function, and then each function is superimposed in time domain;
2) The convolution method of signal and low-pass filter response function is adopted;
3) Rising cosine function of MATLAB
