Lempel Ziv Encoder in matlab

通过编程实现绘图的交互界面以及绘图指令输入框等(Through interactive graphics programming interface and command input box such as drawing)

说明：  图象增强，采用中值滤波和平滑滤波的方式，效果明显(zhongzhi he pinghua)

2PAM和2PPM调制的IRUWB发射机，各种功率、频率、调制方式等参数在start.m中修改(2PAM and 2PPM IRUWB modulation transmitter, all power, frequency, modulation and other parameters to modify in start.m)

水声OFDM通信系统仿真程序，包括信道估计、控制均峰功率比等关键技术，信道为多途信道。(The key technologies for the simulation of the basic OFDM communication system, including the scramble control both the peak power ratio, channel estimation, etc.)

傅里叶变换后频谱图 B：陷波函数作用后的频谱图 C：经逆变换的滤波后图像，效果不是很理想 Ifft2：为验证自己的快速傅里叶变换程序的正确性，用matlab自带逆变换程序将频谱逆变换后图形，与原图相符，说明快速傅里叶变换程序正确。(This is a FFT )

基于matlab苹果颜色分级 rgb转hsv(Based on matlab apple color grading rgb to hsv)

FDTD一维吸收边界条件MATLAB代码(One-dimensional FDTD absorbing boundary conditions MATLAB code)

说明：  HSV颜色空间较RGB空间更适合人的感官视觉，在HSV空间统计图像的分布特征并用于检索比在RGB空间的效果较好。(HSV color space than RGB space is more suitable for people’s senses of sight, in the HSV spatial statistical distribution of the image and is used to retrieve than in RGB space effective.)

高斯信道下BPSK信号的编码和译码，带有完整的说明(Gaussian channel under BPSK signal encoding and decoding, with complete instructions)
