摘　　要：在CDMA的移动通信中,用户数的多少取决于地址码的多少,m序列码是产生地址码的基础。利用移位寄存器可以产生m序列码,在很多数字电子技术教科书中,有介绍过低位m序列码的实现电路,很难找到实现M序列码的电路。通过仿真,用简单的数字电路,设计出实现M序列码的电路。因为M序列码的个数是m序列码个数的2倍,因此具有一定实际意义,而且对设计其它电路也有一定的参考价值。The number of users depends on the number of address code in the CDMA mobile communication, and m se- quence code is the foundation of produce address code. Use of the shift register can produce m sequence code ; there has been introduced to the m sequence code of low code realization circuit in many digital electronic technology textbooks, but it is difficult to find realization of the circuit of M sequence code. Simple digital circuit design is used to realize the M se- quence code by the simulation. Because the number of the M sequence code is 2 times the number of the m sequence code, there are some practical significance, and it has reference value for other circuit design.
