直接将秘密图像的高4bit隐藏在RGB载体图像的R,G,B层中所选的那一层的低4bit(Directly to the secret image hidden in the high-4bit RGB vector images R, G, B layer, then a layer of selected low-4bit)

小波分析 时频工具箱。做小波变换时很有用。大家可以参考。(Time-frequency wavelet analysis toolbox. Useful to do wavelet transform. We can refer to.)

Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, which is where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this to be achieved without undue interference between the users CDMA employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code). Each user in a CDMA system uses a different code to modulate their signal. Choosing the codes used to modulate the signal is very important in the performance of CDMA systems. The best performance will occur when there is good separation between the signal of a desired user and the signals of other users.
