Transform tools have been widely used in many communications applications for more than three decades. Although Discrete Fourier Transform (DFT) is the most widely used transform in most communications problems, Discrete Cosine Transform (DCT) has become the industry standard for image-video compression in multimedia storage and communications.

More recently, subband and wavelet transforms have been forwarded in the literature with their more flexible time (spatial) and frequency localization than the block transforms which might be of a critical feature for some advanced communications and multimedia scenarios. This edited volume treats the emerging communications and multimedia applications of these popular transform techniques. These applications areas include spread spectrum communications, code division multiple access (CDMA) communications, discrete multitone (DMT) modulation for ADSL and VDSL applications, low probability of intercept (LPI) communications, digital audio broadcasting (DAB), audio processing and compression, multimedia compression, image/video watermarking, telemedicine, and others.

This book consists of chapter contributions from prominent researchers in the field. It is balanced with the theoretical depth and the fine details of advanced communications and multimedia applications. It is intended for communications and signal processing engineers, researchers in electrical engineering and applied mathematics, technical management professionals want to follow the recent developments in this field and advanced level graduate students.
