A wireless channel implemenatation in MATLAB

说明：  基于MATLAB的QPSK调制和解调，并包含对原理的解释和讲解(QPSK modulation and demodulation ,based on MATLAB)

一种基于鲁棒自适应的机器人PD控制，由非线性PD反馈和补偿控制两部分组成。(PD control based on robust adaptive robot controlled by a non-linear PD feedback and compensation of two parts.)

Algorithm for multi robot

说明：  智力游戏 十全十美的MATLAB程序解决方法，效率还是不错的(Puzzle MATLAB program perfect solution, the efficiency is still good)

用互相关函数求两周期性信号的时移，为下一步信号处理提供有力支持。(Use cross-correlation function to get shifting of two periodic signal. )

卷积码的维特比译码仿真，主要是仿真误码率曲线。(Convolutional codes Viterbi decoding simulation, mainly simulation BER curves.)

代码给出了基于混合门限带迭代步长的稀疏图像重构。特别地，压缩采样矩阵为抽样傅里叶变换矩阵，利用2D-FFT,大大降低了计算复杂度。(The mixedthreshold sparse image reconstruction with step is given in the package. In particular， the 2D-FFT is used to disign the sample matrix, which can reduce the computational compexity dramatically. )

SPA，处理光谱数据，选择特征点，以便进行下一步操作(SPA processing, spectral data, feature selection, in order to carry out the next operation)

hotelling transformation has been written with help of Matlab 2007a. This technology has been applied to transform images. A test image has been included in the file for explanation. It accpets 256 color map bmp image as input and produces the output.
