本代码是《通信信号处理》课程的大作业相应的代码。主要是通信信号发射端的仿真，具体功能是：1. 产生任意长度的伪随机序列，将序列映射为I,Q两路的信号，2.均方根升余弦滤波器成型. 3.经过通带衰减为3dB的倾斜滤波器（模拟信道衰落效果）4.插零，半带滤波器升抽样。 5.NCO处理单元调制(This code is communication signal processing courses corresponding to the large code. Mainly is the simulation of the communication signal transmitter, the specific functions are: 1. Produce arbitrary length of the pseudo-random sequence, the sequence mapping for the I, Q two-way signal, 2. Raise the root-mean-square filter forming 3. After passband attenuation 3dB tilt filter (analog channel fading effect) 4. Insert zero, half-band filter l sampling. 5. NCO processing unit modulation)
