sift

此文件包含生成swissroll数据集,并用LLE算法进行降维处理,很实用,应该对现在学习流形学习的同学有帮助。(This file contains data sets generated swissroll and dimensionality reduction algorithm with the LLE process, it is useful, it should now learning manifold learning for students help.)

仿真未编码和进行Hamming编码的QPSK调制通过AWGN信道后的误比特率性能(Hamming coding and for the simulation are not encoded by QPSK modulation in AWGN channel, the bit error rate performance)

this file is gradient matlab code.

基于OFDM系统设计的迭代移位线性搜索PTS算法，亲测可用(An iterative shift linear search PTS algorithm based on OFDM system, pro test is available)

说明：  S变换在Matlab中对于信号处理方面的应用(S transform in Matlab for signal processing applications)

说明：  该程序实现了语音数据转换，将一个 wav 格式的文件读入计算机，为语音信号的进一步处理做准备。(The program realize the speech data conversion. It can read a wav file into the pc, which put a way for the speech signal further study.)

说明：  vb语言实现的卡尔曼滤波源程序 （没有测试，输出部分要配合相应的过程）(vb language Kalman filtering source (no test, the output corresponding to tie part of the process))

matlab编写，能够实现局部子空间鉴别分析，含主方法和测试代码，能直接运行(matlab prepared, can achieve local subspace discriminant analysis, including the main methods and test code that can be run directly)

解决线性规划优化问题，在lingo界面中得到广泛的运用(solve linear programming optimization problems, the lingo interface widely used)
