说明：  bppid程序，非常有用，支持一下吧，这书很难找的(bppid program, very useful to support yourself, this book is difficult to find)

本文试图借助其图像处理工具箱函数的支持从工程和实验角度出发, 较为直观地探讨了matlab在遥感图像融合及质童评价中的应用。 文章首先讨论了两种常见的图像融合方法, 并给出matlab平台上实现其算法的程序代码, 然后提出对融合图像进行质童评价的指标, 最后通过相关程序予以实现并得出评价结果。(This article attempts to help its image processing toolbox function and experimental support from the engineering point of view, a more intuitive matlab discussed quality of remote sensing image fusion and evaluation of children. The article first discusses two common methods of image fusion, and gives the platform to achieve its algorithm matlab program code, and then put forward to the integration of image quality evaluation index child, and finally be realized through the relevant procedures and obtained evaluation results.)

This simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. (This simulation script set allows for an OF DM transmission to be simulated.

扩频序列仿真代码，包括主函数，产生序列函数，扩频函数，调制函数，多径衰落函数。(Spreading sequences simulation code, including the main function, the sequence function, spread function, modulation function, multipath fading function.)

这里面包含了多个IEEE多普勒频移估计论文，都是比较经典的算法，对于研究多普勒频移估计的学者很有帮助(It contains a number of IEEE papers estimate the Doppler shift, are more classical algorithm, the study estimated Doppler shift scholar helpful)

可以用于机械结构中个机构或零件的优化分析，设计计算等，还可以用于其他非机械类专业人员学习参考(Can be used to analyze the mechanical structure optimization in a body or parts, design calculation and so on, can also be used for other non mechanical majors learning reference)

图像处理学习的一些源程序，大家参考一下，希望对大家有帮助(Some source of image processing, learning, your reference, we hope to help)

Matlab编程实现似然比测量距离，用于语音识别模块的小程序(Matlab programming likelihood ratio to measure the distance, voice recognition module for small programs)

用曲线拟合的方式估计线性调频信号的初始频率及其调频斜率。得到的效果比较好。(Curve fitting way to estimate the initial frequency and chirp rate of the linear FM signal. Get better.)
