i send the matlab codes for embedded zero tree and se partioning in hierarchial trees in image compression.I also send matlab code for speech compression using rabiner algorithm amd OFDM transceiver design.

提供matlab编程自上而下的思想，适合初学者的入门级教材。(it provides the programming idea from-top-to-bottom for junior engineers. )

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)

GCP是地面控制点的缩写，主要是处理地面控制点的类，包括控制点的读取处理以及写出。(GCP is an acronym for ground control points, mainly handling ground control points, including read and write process control points.)
