    本实验隶属现代数字信号处理,涉及到谱估计和谱分解,对学习数字信号的现代处理方法帮组很大。系统辨识实验实现:输入为功率为1(方差为1)的白噪声信号,通过一个线性移不变(LSI)系统,采用功率谱分析方法实现系统辨识对一个LSI系统进行辨识,并比较最后辨识出的系统与原系统的差别,分别显示出来。 (Experimental realization of system identification: input power of 1 (variance 1) of the white noise signal through a linear shift invariant (LSI) system, using power spectral analysis method of system identification of an LSI system identification, and compare the final system and identify the difference between the original system, respectively, is displayed.)

    说明:  压缩感知(Compressive Sensing(CS),或称Compressed Sensing、Compressed Sampling)。该理论指出:对可压缩的信号可通过远低于Nyquist标准的方式进行采样数据,仍能够精确地恢复出原始信号。该理论一经提出,就在信息论、信号/图像处理、医疗成像、模式识别、地质勘探、光学/雷达成像、无线通信等领域受到高度关注,并被美国科技评论评为2007年度十大科技进展。(Compressed Sensing (Compressive Sensing (CS), known as Compressed Sensing, Compressed Sampling). The theory states: compressible signal can be much lower than the Nyquist criterion for sampling data, and still be able to accurately recover the original signal. The theory was put forth, to receive significant attention in the field of information theory, signal/image processing, medical imaging, pattern recognition, geological exploration, optical/radar imaging, wireless communications, and Technology Review named the 2007 top ten scientific and technological progress.)
