Multipath_Narrowband-_channel

pca_new程序是一个用于降维的程序。用于降低数据的维数，更好精简冗余信息。(pca_new.m is used for data dimention reduction.)

main executing reference usage: usage_overlayColoredBorders_Images.m The objective is to illustrate overlaying of 2 RGB images. Multiple images may be overlay 1 over the other as well.

Audio compression and recording

说明：  牛顿迭代分形,非常漂亮的3D抽象分形物，用matlab打开(Newton fractal, very beautiful, 3D abstract fractal objects, opens with matlab)

Compute image RGB histogram

this program is a sample program for connecting MATLAB with Xplane9 using UDP comunication.

该程序用以对2FSK信号调制解调的仿真程序，信道为高斯白噪声，采用FFT方法对其解调(procedures for the right 2FSK signal modulation and demodulation of the simulation program, channel for white Gaussian noise, FFT method demodulation)

地震波正演模拟 吸收边界 matlab(Seismic forward simulation of absorbing boundary matlab)

根据系统辨识的系统模型，采用KALMAN滤波算法，根据期望信号和观测信号求未知的系统。(According to the system model system identification, using KALMAN filtering algorithm, based on the desired signal and the observed signal seeking unknown system.)

DUNE (Distributed and Unified Numerics Environment)，分布和统一数值解环境，是一种求解偏微分方程的基于网格的方法（PDE）的模块化的工具箱。DUNE是所有这些体现了科学计算的概念从抽象的接口设置第一次。现代C + +编程技术使同样的概念非常不同的实现使用一个非常低的开销一个共同的接口。因此，DUNE确保在科学计算的效率，并支持高性能计算应用。(DUNE (Distributed and Unified Numerics Environment), distribution and unified numerical solution of the environment, is a solution of partial differential equations of the grid-based methods (PDE) of the modular toolbox. DUNE is that all these reflect the concept of scientific computing from the abstract interface settings for the first time. Modern C++ programming techniques to the same concept is very different implementations use a very low cost of a common interface. Therefore, DUNE ensure the efficiency of scientific computing, and supports high-performance computing applications.)
