infinite impulse response filters (IIR).. included LPF,HPF, BPF and BSF.. both butteworth and chebyshev..

There are many compressed sensing (CS) recovery algorithms that have been proposed. Here I list some of them, and provide the corresponding experimental results. Essentially, the recovery algorithms are similar to the sparse coding based on the over-complete dictionary.

给原始信号加入噪声，然后让信号经过卡尔曼滤波器，比较原始信号、加噪声后信号及通过卡尔曼滤波器的信号的图像。(Adding noise to the original signal, and then let the signal through the Kalman filter, compare the original signal, the signal plus noise and the signal through the Kalman filter images.)
