信号由三个频率分别为0.01，0.1，0.2的正弦信号组成。 (1)作信号的连续小波变换。 (2)自己选择小波基数，对信号进行多尺度分解，将每一个正弦信号分开。 (3)重建原信号。 (Signal from the three frequencies were 0.01,0.1,0.2 sinusoidal signals. (1) continuous wavelet transform for signal. (2) choose the wavelet base, multi-scale decomposition of signals, a sinusoidal signal of each separate. (3) reconstruction of the original signal.)

对一个信号进行奇异值分解，根据差分谱最大值点，重构信号，达到降噪的目的。(Signal for a singular value decomposition, according to the differential spectrum maximum point, the reconstructed signal to achieve noise reduction purposes.)

说明：  使用MATLAB对MIMO系统进行辨识，其中有各种算法仿真算例，N4SID，针对多变量系统的一种识别算法(MOESP (Multivariable Output-Error State sPace) is a deterministic method to identify linear time invariant systems. The MOESP method developed by M. Verhaegen and P. Dewilde is based on the LQ decomposition of Hankel matrix formed from input-output data, where L is lower triangular and Q is orthogonal. A Singular Value Decomposition (SVD) can be performed on a block from the L (L22) matrix to obtain the system order and the extended observability matrix. From this matrix it is possible to estimate the matrices C and A of state-space model. The final step is to solve overdetermined linear equations using the least-squares method to calculate matrices B and D.)
