摘　　要：扩频通信的种种优势源于伪随机码具有随机性,尖锐的自相关特性和较小的互相关值。文中介绍了伪随机码中最普遍的m序列的原理、性能和构造方法。考虑到计算机C语言普及率高和可移植性强的特点,文中给出了基于计算机C语言m序列生成源程序和m序列基本性质的成图结果。The various advantages of spread spectrum communication result from the randomness,sharp autocorrelation and small cross-correlation value of the pseudo-random codes.This paper introduces the principle,performance and construction methods of the most popular sequence code-pseudo-random m.Besides,taking into account the high penetration and portability of C language,this paper presents the source program of generating m sequence and the mapping results of m sequences based on C language.This concise method can provide suitable reference for engineers and technicians.
