利用一般最小二乘法和SVD-TLS方法 进行AR参数估计和正弦波频率估计 -use of general and the least-squares method SVD-TLS AR method parameter estimates and the estimated frequency sine wave

svd分析的例子，程序，生成数据，预处理，分析-SVD analysis of the examples, procedures, generating data, pretreatment, analysis

用AR模型估计信号的功率谱的仿真:分别用svd-TLS的方法，4阶AR模型，100阶AR模型仿真信号-With the AR model to estimate the power spectrum of the simulation: each method of using svd-TLS, 4-order AR model, AR model order of 100 simulated signal
