IRIS_Tbx_8_20110420a

This program is used to Simulate the performance of (n,k)Reed Solomon code in AWGN channel with plotting the results and compare with the theoretical performance of this code in AWGN channel. The program also print the SNRdB, absolute snr ,simulated probability of error, exact probability of error in each steps

用四阶龙格库塔法求非线性系统的输入相应，同时用simulink建模比较。 (Using fourth-order Runge-Kutta method for the corresponding input nonlinear systems, and modeling using simulink comparison.)

ICA watermarking. Blind, fragile, robust

说明：  语音信号的LPC参数提取及合成，可以提取基音及残差信号(LPC parameters of speech signal extraction and synthesis, and the residual signal can be extracted pitch)

改进节点法建立MNA方程 matlab算法，附有设计文档(Modified nodal equations matlab algorithm established by MNA)

在matlab中，实现图像旋转（两种方法：临近法、双线性法）(In matlab, the realization of image rotation (two methods: near the bilinear method))

Simulink models of PV modules .

本程序实现QPSK信号，通过瑞利信道后的各部分星座图(The program QPSK signal, Rayleigh channel through each part of the constellation after)

Description All the filters have needed neighbor data the current pixel in the image,here this function(res_window=cover_window(how many neighbor value for row ,how many neighbor value for column ,input image) produce the result( res_window(row,col,total size)) input inp_img=2d data(row * col) w=cover size w=[3 3] = 3x3 cover pixel generation output o_img=result 3d o_img(w(1),w(2),r*col) if inp_img=[1 2 3 4 5 6 ] w=[3 3] Soloution it will construct new image new_img=[0 0 0 0 0 0 1 2 3 0 0 4 5 6 0 0 0 0 0 0] result o_img(:,:,1)=[0 0 0 0 1 2 0 4 5] o_img(:,:,2)=[0 0 0 1 2 3 4 5 6] finally o_img(1:3,1:3,6) example a=imread( pears.png ) b=rgb2gray(a) c=cover_window( b,[3 3]) 3x3 window construction

说明：  K-MEANS算法是输入聚类个数k，以及包含 n个数据对象的数据库，输出满足方差最小标准的k个聚类。 (K-MEANS algorithm is the input number of clusters k, and n a data object that contains the database and output to meet the standard minimum variance k-clustering.)
