摘　　要：在扩频系统中通常采用扩频序列对信号进行频谱扩展,因而扩频序列对系统性能起着决定性作用,伪随机序列中的m序列为最常用的基本序列,介绍了m序列的原理,性能及产生方法,并在MATLAB中进行了实现和分析,仿真结果表明了该方法的正确性和可行性。To expand the signal spectrum in spread spectrum system, the signal spectrum is generally expanded by a spread spectrum sequence. The character of spread spectrum sequence affects the communication quality. In all PN sequences,m sequence is often used as basic spread spectrum sequence. The brief introduction to the theory.property and genernation means of the m sequences is given first, and the generation and analysis by programming with MATLAB are given. The simulation results show the validity and feasibility of this method.
