直接系列扩频通信系统的频谱扩展是借助于扩频函数而实现的，典型的扩频函数就是伪随机序列码。
Spectra expanding of Spread spectrum communication system makes use of the spread spectrum function to realize, the typical spread spectrum function is pseudo random sequence code.
伪随机码绝对式编码器采用M序列伪随机码作为编码方法，采用双狭缝技术进行分时位置读取，并采用ROM元件进行译码输出。
M sequence pseudorandom code is used for encoding the pseudorandom code absolute encoder, double slit technique is used to perform time sharing reading and ROM is used as the coding device.
结果显示：理论上采用双极性纯随机序列作为地址码可以使多址干扰达到最小，而在实际应用中伪随机m序列作为地址码也使多址干扰趋向最小。
The results show that MAI is minimized if pure random sequences are used as address codes, and m sequences are appropriate substitutes for pure random sequences in practice.
