AR过程的线性建模与功率谱估计，计算其自相关序列的估计，利用所估计的自相关值和Yule-Walker法(自相关法)，估计系数值。(The linear AR process modeling and power spectrum estimation, calculation of the estimated autocorrelation sequence, using the estimated autocorrelation values and Yule-Walker method (autocorrelation method), the estimated coefficient.)

对初学者适合的matlab命令集学习，还是很不错的，查找语句时有帮助(Right of the matlab command set suitable for beginners to learn, still very good, to find statements from time to time to help)

利用MATALB产生数据表并以.mif文件格式保存(create a .mif documents by MATLAB)

宽带信号的空间谱估计以及信噪比等对信号估计的影响，才用聚焦矩阵的方法，采用的聚焦矩阵不同，性能也不同，这里是RSS算法(Spatial spectrum estimation of wideband signals and SNR of the estimated impact on the signal only with the focusing matrix method, using the focusing matrix of different, performance is different, here is the RSS algorithm)
