Compressive sampling is an emerging technique that promises to effectively recover a sparse signal from far fewer measurements than its dimension. The compressive sampling theory assures almost an exact recovery of a sparse signal if the signal is sensed randomly where the number of the measurements taken is proportional to the sparsity level and a log factor of the signal dimension. Encouraged by this emerging technique, this thesis briefly reviews the application of Compressive sampling in speech processing. It comprises the basic study of two necessary condition of compressive sensing theory: sparsity and incoherence. In this thesis, various sparsity domain and sensing matrix for speech signal and different pairs that satisfy incoherence condition has been compiled.

建立前馈预测控制系统，比较原始信号、前馈预测信号和反馈控制信号的特征，体现前馈预测控制的精确性，前馈因子可调。程序运行后观察示波器图形即可。(Create feedforward predictive control system to compare the original signal, the the feedforward prediction signal and the feedback control signal, characterized in, reflects fed predict the accuracy of the control, feedforward factor is adjustable. Oscilloscope graphics can be observed after the program is running.)
