用专家系统优化下面的PID参数或设计一个专家控制器，被控对象为 并与PI控制算法进项比较(use expert system optimization below the PID parameters, or a design expert controller, and object to the PI control algorithm with a credit comparison)

毕业设计的基于8QAM+zcz序列的准同步CDMA通信系统仿真(　　　This article will be given below 8QAM+ ZCZ sequence sets up method and analysis, will further introduce the relevant definitions zero correlation sequence and some properties and characteristics, including non-cycle related, cycle-related, Qi cycle and other characteristics. The reason why is because the study of these theories using this sequence, in the Gaussian channel conditions and system performance in terms of interference is very similar to the synchronization system and the system performance is far superior to an asynchronous system, and the extended sequence comparison the original sequence has better performance.)

包含Matlab课件及源程序，对Matlab的基本理论和实际中的应用进行描述，有利于MatlaB的自学。(Includes courseware and Matlab source code, the basic theory of Matlab and practical application in the description of the self in favor MatlaB.)

说明：  谱估计中的自回归模型（AP）算法，适合阵列信号处理初学者学习(Spectral Estimation autoregressive model (EM) algorithm)

对于周期图的功率谱估计,当数据长度N太大时,谱曲线起伏加剧, 若N太小,谱的分辨率又不好,因此需要改进。两种改进的估计法是 平均周期图法和平滑平均周期图法。Bartlett法:Bartlett平均周期图 的方法是将N点的有限长序列x(n)分段求周期图再平均。(For the power spectrum estimation of the periodogram, when the data length N is too large, the spectral curve fluctuation intensifies,   If N is too small, the spectral resolution is not good, so need to be improved. The two improved estimates are   Average Period Graph and Smooth Mean Period Graph. Bartlett method: Bartlett average cycle chart   Is to re-average the finite-length sequence x (n) of N points by periodogram.)
