SIFT PCA MATLAB实现

灰度图像质量评价，以matlab为平台，介绍了几种关于灰度图像算法的质量，以数据结果来说明图像的质量。(Gray image quality evaluation, in order to matlab as a platform to introduce several gray image algorithm on the quality of data to illustrate the results of image quality.)

To make parameters easier to change and easier to determine their values, a GUI is supplied with this model. Radar and weather parameters may be changed from this GU

matlab角点检测的程序，图像中所有凹凸点都可以检测到，并在二值图像上显示出来，效果不错。直接运行corner.m即可

主要是QAM与16PSK频谱仿真、误码率比较仿真以及各自的星座图(Mainly QAM spectrum with 16PSK simulation, emulation, and error rate between the respective constellation)

一种用于判决反馈均衡器的方法和装置，其中使用一校正项来补偿限制器误差，从而避免了误差传播。选择均衡器的滤波器系数以便使均衡器的代价函数最小(One for decision feedback equalizer method and device, which uses an error correction terms to compensate for the limiter, thus avoiding error propagation. Select equalizer equalizer filter coefficients so that the minimum cost function)
