噪声中非平稳信号频谱分析

利用运动目标检测中的帧差法对视频中的行人进行检测和跟踪，取得了比较好的效果，可以学习借鉴。(The use of moving target detection in the frame difference method for video of the pedestrian detection and tracking, to obtain a relatively good results, can learn from.)

此程序是在MIMO-OFDM系统中，利用角度域进行信道估计，选用DFT的插值方法进行！希望对研究角度域信道估计的人有所帮助！(This procedure is in the MIMO-OFDM system, using the angle domain channel estimation, the selection of DFT interpolation method! I hope to study angle domain channel estimation of some help!)

本书详细介绍了基于近场测试数据的逆散射问题的相关知识及其具体应用，这是近场问题的一个很好的例子，在人们都关注高频远场问题的背景下，提出近场的问题，对于计算电磁学的发展很有启发意义，我们的工程实际中，除了高频远场的应用外，低频近场也占有很大的份额，基于进场的反演是一个新兴的课题，需要我们共同去研究！(Book introduced in detail based on near field test data of the inverse scattering problem related knowledge and its practical application, this is a very good example of near field problems, people are concerned about the background of far field problem of a high frequency in the, near field is proposed, for the development of electromagnetism calculation is instructive. In the actual engineering, in addition to the high-frequency far field of application, low frequency near-field also occupies a large share of, based on the inversion approach is a new and developing subject, we go to study!)

无限长的序列也往往可以用有限长序列来逼近。对于有限长的序列我们可以使用离散傅立叶变换（DFT）。DFT是对序列傅立叶变换的等距采样。是序列傅立叶变换的等距采样。 本源码是对DCT、DFT、FFT的matlab实现(Infinitely long sequence is often a long sequence with limited approximation. For the finite length of the sequence we can use the discrete Fourier transform (DFT). DFT is a sequence of equidistant sampling Fourier transform. Is a sequence of equidistant sampling Fourier transform. The source is the DCT, DFT, FFT in matlab implementation)
