说明：  mylsb.m是个非常完整的LSB密写源码并且密写和提取都在里面，图片我没上传，你只需要添加一个图片文件就可以了，记住图片必须是灰度图片，如果是RGB，我转换的代码也在里面很有意思哦。weipingmian.m是个提取图像位平面的程序，图片也是需要你自己加载，最后一个就是8*8块的图像DCT变换。(mylsb.m is a very complete source of LSB Steganography Steganography and extraction, and are on the inside, I did not upload pictures, you only need to add a picture file on it, remember the image must be a grayscale image, if it is RGB, I converted the code is also very interesting inside Oh. weipingmian.m is a program to extract bit-plane images, pictures, you also need to load the last one is 8* 8 DCT transformed image.)

Quadrature amplitude modulation (QAM) is a modulation scheme in which two sinusoidal carriers, one exactly 90 degrees out of phase with respect to the other, are used to transmit data over a given physical channel. One signal is called the I signal, and the other is called the Q signal. Because the orthogonal carriers occupy the same frequency band and differ by a 90 degree phase shift, each can be modulated independently, transmitted over the same frequency band, and separated by demodulation at the receiver. For a given available bandwidth, QAM enables data transmission at twice the rate of standard pulse amplitude modulation (PAM) without any degradation in the bit error ratio (BER).
