Adaptive Filtering Applications

Издательство InTech, 2011, -410 pp.Adaptive filtering is useful in any application where the signals or the modeled system vary over time. The configuration of the system and, in particular, the position where the adaptive processor is placed generate different areas or application fields such as: prediction, system identification and modeling, equalization (deconvolution, reverse filtering, inverse modeling), cancellation of interference, etc. which are very important in many disciplines such as control systems, communications, signal processing, acoustics, voice, sound and image, etc. This book consists of a compendium of applications in three areas of great interest in scientific research: noise and echo cancellation, medical applications, communications systems and others hardly joined by their heterogeneity. There is no a structure and/or algorithm better than other; It all depends on the implementation and the performance target. In all these chapters, each application is a case study with rigor that shows the weakness‐strength of the method used (in many cases compared with other methods), assesses its suitability and suggests new forms and areas of use. The problems are becoming increasingly complex and applications must be adapted to solve them. The adaptive filters have proven to be useful in these environments of multiple input/output, variant‐time behaviors, and long and complex transfer functions effectively but fundamentally to be still evolving. There are many variables to take into account and how to combine them, optimize them and achieve the desired outcome. This book is a demonstration of this and a small illustration of everything that is to come.
