Introduction and Overview
The technical community has witnessed recently a resurgence of activity involving the theory and design of linear systems for signal decomposition and reconstruction. Over the past few years, there have been considerable advances in multirate signal processing, with much of the attention being given to subband decompositions and wavelet transforms. These advances in algorithm theory combined with advances in microelectronics technology enable cost-effective digital computer processing of signals to be performed, and has attracted great interest in the signal processing and telecommunications areas. The influence of subband and wavelet representations can be seen in many important areas, such as teleconferencing, telemedicine, video transmission for unmanned autonomous vehicles, high definition television, picture phones, voice identification, speech recognition, secure voice transmission, signal storage, object detection and classification, and many others.
