本程序仿真CDMA2000的复扩频过程,只考虑导频信道和一个业务信道,假设同步已建立，接收端能产生同频同相相干载波,整个仿真过程在基带中进行.-The simulation program CDMA2000 complex spread spectrum, considering only the pilot channel and a business channel, and assume that synchronization has been established, the receiver can produce the same frequency and phase coherent carrier, the whole simulation process in the baseband
