Presented in a tutorial format with hundreds of figures and tables, this handbook makes signal processing as applied to digital communications accessible for all professionals, researchers, and students involved in mobile communications. Adaptive Multichannel Time Delay Estimation. This book examines signal processing techniques for cognitive radios. Joseph Boccuzzi, a leading signal processing expert with years of product development, research, and teaching experience, this on-target engineering tool takes readers step by step through major wireless topics. The book addresses several aspects related to the quality perception of entire video calls, namely, the quality estimation of the single audio and video modalities in an interactive context, the audiovisual quality integration of these modalities and the temporal pooling of short sample-based quality scores to account for the perceptual quality impact of time-varying degradations. Averaging Techniques for Envelope Estimation.
Since both the desired speech and undesired noise are filtered at the same time, the most critical issue of speech enhancement resides in how to design a proper optimal filter that can fully take advantage of the difference between the speech and noise statistics to mitigate the noise effect as much as possible while maintaining the speech perception identical to its original form. The Book Also Will Contain Matlab Script Files That Implement The Examples As Well As Design Tools For Filters Similar To The Examples. Unique in covering both traditional antenna theory, antennas in imaging systems and the most recent developments in adaptive antenna technology in depth, the book's main emphasis is on theoretical understanding and design.
