Study of steganographic techniques for digital images

Steganography, meaning hidden writing, is the technique of concealing secret information into another cover-media, such as audio, video, image and text, in such a manner that the very existence of the information is camouflaged. Unlike the goal of cryptography, which prevents the data from illicit access and modification by transforming the secret data into messy and meaningless bit-streams, the aim of steganography is to conceal their very existence such that the embedded data is inaudible or invisible to the grabbers.

Multiuser detection and power control in CDMA systems

Currently, code-division multiple access (CDMA) technique continues to be a dominant air-interface technology for personal wireless communication systems. Mobile communication systems based on CDMA is always subject to multiple access interference (MAI) problem due to the difficulty in maintaining orthogonality of CDMA signals in a mobile environment.
