基于MATLAB的伪随机序列的产生和分析

MATLAB由于其强大的功能而被广泛应用于很多工程领域。在扩频通信中通常的做法是用一扩频序列与信号相乘，从而得到频谱的扩展或压缩，因而扩频序列的性能直接决定着通信质量。伪随机序列中的m序列和Gold序列最常用作扩频序列。该文首先简单介绍了m序列和Gold序列的原理，性能和构造方法，接着在MATLAB中用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。

Generation and Analysis of PN Sequence Based on MATLAB

MATLAB software has been used extensively in many engineering fields due to its strong operation fanction. To expanding or compressing the signal spectrum in spread spectrum system, the signal is generally multipled by a spread spectrum sequence. The character of spread spectrum sequence significantly affects the communication quality. In all PN sequences, m-sequence and Gold-sequence are often used as spread spectrum sequence. In this paper, the brief introduction of the theory, property and constructing means of the two sequences are given first,and the generation and analysis of them by programming with M language in MATLAB are given later. The simulation results show the correctness and feasibility of this method. The simple and intuitive method is convenient for the engineering personnel.
