MATLAB中利用吉洪诺夫正则化和L曲线求解病态方程组(L-Corner to solve ill-posed)

本代码实现基本的GMSK调制解调的功能，经过调试可用(The code to achieve basic GMSK modulation and demodulation functions available through debugging)

时延估计算法ETDE，经过测试性能良好，共同学习讨论(The time delay algorithm ETDE)

FFT变换(快速傅立叶变换) 用于学生实验参考例程(this folder includes FFT transform and some reference examples for students to experiment)

DVB-T，DTMB简化的信道仿真程序。设置了三种保护间隔：循环前缀、零添加、伪随机添加。用于研究不同保护间隔下的SNR特性，附带一个不同保护间隔下的频谱显示，可看出三种保护间隔对OFDM频谱陡峭程度的影响。(DVB-T，DTMB channel simulation and spectrum display.)

这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。(Where k-means clustering, is given in advance the number of classes contained in the original data, then the data contained similar characteristics grouped into a single class.)

是在时域上做相关，直接用covn做相关，计算量比较大，估计比较明显。(Is done in the time domain correlation and directly related with covn, calculate than the larger, more obvious estimate.)

Kohonen and CPANN toolbox是开发的一个MATLAB工具箱，用来对数据结构进行研究和分类。(The Kohonen and CPANN toolbox is a collection of MATLAB modules for developing Kohonen Maps and Counterpropagation Artificial Neural networs (CPANNs). These are well known neural networks aimed to the study of data structure (Kohonen Maps) and to the data classification (CPANNs). )

AdaBoost, short for Adaptive Boosting, is a machine learning algorithm, formulated by Yoav Freund and Robert Schapire. It is a meta-algorithm, and can be used in conjunction with many other learning algorithms to improve their performance.
