基于MATLAB环境的音频水印提取源程序（非盲水印）(MATLAB-based environment for audio watermark extraction source (non-blind watermarking))

可以根据不同的设计指标参数，快速、有效、自动地完成低通、高通、带通、带阻等各种滤波器的设计和仿真计算，直观展示相应滤波器的幅频、相频特性。(According to different parameters design specifications, fast and effective, automatically complete low pass, high pass, band pass, band stop filter design and various simulation, visual display appropriate filter frequency, phase frequency characteristics.)

说明：  Damp control for UPFC 2

验证可用，分析了该信号的时域、频域、倒谱，循环谱等,构成不同频率的调制信号。( Verification is available, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Constituting the modulated signals of different frequencies.)

MS-AR：马尔科夫取值转移自回归模型，状态可取两种状态，也可以取多种状态。(MS-AR：the program of Markov Switching autoregressive model.)

移动最小二乘的MATLAB程序 用于简单的散点曲线拟合(MATLAB Program of Moving Least Squares for Simple Spot Curve Fitting)

该程序为RLS算法性能分析的MATLAB程序。(RLS algorithm)

改进等高线拟合代码，很有价值。(improve contour fitting code and of great value.)
