transmission using uncoded bpsk modulated data

The code implements the following paper: Guorong Xuan, Jiang Zhu, Jidong Chen, Shi Y.Q., Zhicheng Ni, Wei Su, "Distortionless data hiding based on integer wavelet transform" IET Electronics Letters, Volume: 38, Issue 25, page 1646- 1648, December 2002. (ISSN: 0013-5194) The watermark embedding and extraction modules have been implemented separately. The watermark embedding module embeds the watermark using bitplane compression in the integer wavelet transform domain. The watermark extraction module extracts the previously embedded watermark and restores the original image. A logo image is used as a watermark but can be replaced with any thing.

霍夫曼coding程序，用此程序可以对任意图像进行霍夫曼编码。(Huffman coding procedures, this procedure can be used for any image Huffman coding.)

说明：  这一程序主要分析了辅助变量最小二乘法，运用地推算法。(This program analyzes the least squares method of auxiliary variables, the use of ground projection method.)
