MUSIC-MATLAB

仍然是卷积码的代码，是matlab的，最近写这方面的论文，找了很多(Convolutional code is still code, is matlab, recently wrote this paper to find a lot of)

Bit-Error-Rate Simulation Using Matlab

使用matlab实现rz码的编码,通信原理实验之一(use Matlab achieve rz codes, one communication principle experiment)

里面有多个多普勒频移估计的高质量文章，不同的温江介绍不等的算法，有几个会有相似之处，在我看来这是非常好的多普勒频移估计的IEEE文章，希望对大家有用！(There are more than the estimated Doppler shift quality paper, different algorithms ranging Wenjiang introduction, there are several similarities, in my opinion this is a very good estimate of the Doppler shift of IEEE article, we hope to useful!)

About Kalman Filter/control system

用最小生成树的方法来求解最短的送货路径，并画出生成树图形(With the minimum spanning tree method to solve the shortest delivery path and draw spanning tree graph)

本文用龙格库塔法求解了不拉休斯解。龙格库塔法是求解高阶微分方程的有力工具，本文对龙格库塔方法作了简要介绍，并附上了matlab源程序。(in this paper a runge_kutta method was used to slove the blasius equation in the environment of matlab.)

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)

说明：  计算时变重力场变化的程序，通过此程序可以计算地球质量变化等等。(Changes in time-varying gravity field calculation program, this program can be calculated by changes in Earth' s mass and so on.)

基于多元线性回归分析的耦合通道参数化建模(Coupled channel parametric modeling based on multiple linear regression analysis)
