Newton-convex-optimal

This is the CRB caculated for an OFDM system to compair belind channel estimation. CRB is Cramer Rao bound and it is the lowest bound for analyzing the devlopement of algorithms of channel estimation.

用MATLAB实现的自相关的算法源程序，不错(Using MATLAB realize the auto-correlation algorithm source code, it is true)

Graphical Interface using the matlab platform for Content based image retrieval.

说明：  简单的对图像进行锐化和平滑处理的函数，运行test函数即可，图像包含在文件中。(Simple sharpening and smoothing the image processing function, you can run the test function, the image contained in the document.)

遗传算法改进的模糊C均值聚类的matlab源程序,可以运行,格式需要更改(Improved genetic algorithm fuzzy C means clustering matlab source code, you can run, you need to change the format)

数字图像处理中所用的灰度加权法，matlab源代码，用于处理图像求质心点坐标(Digital image processing method used in the weighted gray, matlab source code, image processing is used to find the centroid point coordinates)

QPSK信号通过瑞利衰落信道后的误比特率和误符号率，并与AWGN信道下的误比特率和误符号率进行对比。其中，多普勒频移为 100Hz，经过矩形脉冲成形后的抽样时间间隔为1/800000s。(The QPSK signal harms the bit rate after the Rayleigh fading channel and harms the mark rate, and harms the bit rate with the AWGN channel under and harms the mark rate to carry on the contrast. And, the Doppler shift is 100Hz, after undergoing the square pulse forming the sampling time gap is 1/800000s. )

说明：  利用matlab处理数据.采用FFT和小波分析的方法分析信号的功率谱.........(perform on the picture using matlab to analysis the power spectrum...)

This model shows the implementation of a QPSK transmitter and receiver. The receiver addresses practical issues in wireless communications, e.g. carrier frequency and phase offset, timing offset and frame synchronization. The receiver demodulates the received symbols and outputs a simple message to the MATLAB command line.

说明：  介绍了matlab中的数据归一化，并结合实例分析了归一化具体步骤及用ANN进行预测的方法。(Matlab introduced in the data normalization with examples of the normalized specific steps and methods used ANN to predict.)
