QPSK--rici

OFDM检测的仿真，通过计算OFDM的归一化4阶累积量，实现OFDM信号的判决，内含升余弦滚降滤波或内插滤波的频谱图(OFDM simulation test, by calculating the normalized OFDM 4th order cumulant, to achieve decision OFDM signal, containing Raised Cosine filter or interpolation filter of the spectrum)

本程序采用单阈值量化法产生混沌序列并仿真其游程特性(This program uses a single thresholding method of generating chaotic sequences and simulation run-length features)

详细的汉明码讲解及编程，本程序只适用传送语音信号等N*1维的矩阵数据，要是想传送灰度或者彩色图片，需要修改一下。(Hamming code in detail to explain and programming, this procedure applies only to transmission of voice signals, such as N* 1-dimensional matrix of data, if would like to send grayscale or color images, the need to make some corrections.)

说明：  众所周知，turbo码是cdma2000中一项重要的技术，该程序用simulink模拟实现turbo编码(As we all know, turbo code is an important cdma2000 technology, the process simulation using simulink realization of turbo coding)

说明：  这是初学者学习Matlab的经典课件，第一到五章，包含微积分问题、线性代数问题以及数据拟合方法等(This is the classic beginner learning courseware Matlab, first to the five chapters, including the issue of calculus, linear algebra problems, and data fitting methods)

基于PCA的Isodata聚类算法matlab实现(Isodata algorithm based on PCA method)

在matlab下，使用hough 算法检测圆形( matlab hough cicle)

自己的数字信号处理第三版的课后实验作业，有兴趣的可以参考参考。(Its own digital signal processing of the third edition of the after-school lab assignments, who are interested can refer to reference. !)
