Code

PCM编码把模拟信号转换为数字编码，在通信电路的目的地，脉冲调制解调器将二进制的数字编码重新转换成那些在调制器中有相同量子水平的脉冲。(PCM encoding to convert analog signals to digital encoding, the destination of the communication circuit, the binary pulse modem re-converted into digital code modulator in which the quantum level of the same pulse.)

说明：  直接序列扩频通信系统建模与仿真 PN码序列产生代码（matlab)(PN code sequence generated code (matlab))
