数字预失真--用于产生WCDMA 仿真信号源等程序(DPD--make_pulse_with_ballast.m and so on)

扩频通信系统仿真 ——系统将基带信号（即信息）的频谱扩展至很宽的频带上，然后再进行传输，即将欲传输的信息数据用伪随机序列编码调制，实现频谱扩展，然后通过信道编码发送出去；接收端采用与发送端完全相同的伪随机序列作为本地解扩信号进行相关处理，以恢复信息，最后进行解调，完成整个系统的接收。(Simulation of spread spectrum communication system- the system baseband signal (ie, information) be extended to a wide spectrum of frequency bands, and then transferred, will want to use transmitted information data sequence of pseudo-random code modulation, to achieve expansion of the spectrum, and then sent channel coding receiver and transmitter use the same pseudo-random sequence as related to the local despreading signal processing, in order to restore the information, the final demodulation, the receiver to complete the system.)

关于信源编码和信道编码的源程序，信道编码包括NRZ码及其频谱分析，信道编码是关于RS码的分析(About the source code of the source coding and channel coding, channel coding NRZ code and its spectrum analysis, channel coding on the analysis of RS code)
