Multi variable control tool

说明：  用matlab程序模拟实现cdma系统的整个过程。包括并串、串并转换，m序列的产生，直接扩频、解扩，qpsk的调制解调，载波调制解调等。(Matlab simulation procedures used to achieve the whole process of cdma systems. Including and string SERDES, m sequence generation, direct spread spectrum, despreading, qpsk the modulation and demodulation, carrier modulation and demodulation, etc..)

本程序，对三维重建的结果调试已通过，得到很好的实验结果，方便大家学习。(This procedure, the results of three-dimensional reconstruction of debugging has passed, get a good result, we facilitate learning.)

函数回调实例。用M文件可以更好的把握整个程序的全局，更能方便的实现函数回调。(Function callback instance. M-file can be used to better grasp the overall situation of the whole process, more convenient to implement the function callback.)

一维最小二乘无网格法matlab程序 可参见张雄无网格专著(One-dimensional least squares meshless method matlab program can be found in Zhang Xiong meshless monograph)

particle filter paper in a code, a total of papers in the code implementation mentioned in matlab+ C

说明：  自动化指纹识别，操作简便，代码运行快捷。(fingerprint identity)

基于Matlab的米勒编码仿真 实现RFID的Miller编码 (Miller coding to achieve)

图像进行小波分解后，对于相对来说不重要的高频成份采用较高的阈值，进行高压缩；而对集中图像大部分能量的低频成分采用较小阈值，以确保图像恢复时的质量(Image Compression)

基于维特比译码算法的BPSK解调方式，survivor_state是一个矩阵，它显示了通过网格的最优路径，这个矩阵通过一个单独的函数metric(x,y)给出，这个算法既能用于硬判决译码也能用于软判决译码。 (BPSK demodulation method based on viterbi decoding algorithm, survivor_state is a matrix, the optimal path of it shows through the grid, the metric matrix through a separate function (x, y), the algorithm can not only used for decoding hard decision can also be used to the soft decision decoding. )
