说明：  由十其强人的功能而被广泛应{IJ十很多工程领域。在扩频通信，}，通常的做法是{IJ扩频序列J信号和乘， 从而得到频谱的扩展或扭缩，因而扩频序列的性能直接决定着通信质量。伪随机序列，}，的m序列和Cold序列最常{}J们一扩 频序列。该文首先简中介绍了m序列和Cold序列的原理、性能和构造方法.接着在MAfLAB }}})IJ M语言编程实现它们的产 生和分析。仿真结果验证了该方法的正确性和可行性。该方法简练直观，适合工程技术人员参考。
(From ten of its functions strongman widely (IJ ten should be a lot of engineering fields. In spread spectrum communications,), the usual practice is spreading sequences (IJ and J signal x, resulting in the expansion of the spectrum or twisting shrinkage, thus the performance of direct sequence spread spectrum determines the quality of communication. Pseudo-random sequence,), the m sequence and Cold sequence () J are the most common one spreading sequences. The article first introduces Jane m sequences and sequences Cold Principle, performance and construction methods. Then MAfLAB)))) IJ M programming language to achieve their production and analysis. The simulation results confirm the correctness of the method and feasibility. The method is concise and intuitive for engineering and technical staff.)
