本文主要利用matlab编程工具对直接序列扩频通信的捕获过程进行仿真。仿真主要基于滑动相关法的有关理论,先讨论扩频仿真中起着重要作用的m序列的生成问题,尔后讨论调制信号的产生,然后在信号的捕获中分步讨论,先对捕获的流程进行简单的仿真,再依次加入噪声和多普勒频移后进行捕获仿真(In this paper, using matlab programming tools for direct sequence spread spectrum communication capture process simulation. Simulation of the sliding correlation method is based on the theory, first discuss the simulation plays an important role in spreading the m sequence generation problem, the modulation signal generation and later discussed, and the signal captured by stepping discussion processes the captured first simple simulation, and then followed by adding noise and Doppler frequency shift after the capture simulation)

说明：  非性多变量系统递归辨识算法，同时, 也对这些算法的估计一致性问题进行了讨论，具有效果还可以(Recurrent identification algorithms for non-linear multivariable systems are discussed. The estimation consistency of these algorithms is also discussed. The results show that the algorithm is effective and can be used to identify non-linear multivariable systems.)
