This is a handbook on intelligent adaptive communication techniques for sake of better data rates achievement along with maintaining the desired Quality of Service (QoS). In this regard, various evolutionary/soft computing techniques has been investigated. Fuzzy systems, Evolutionary algorithms and Neural Networks are the major techniques employed for sake of adaptive communication. Moreover, the hybrid versions of these techniques have also been explored for better results. The book is a comprehensive guide for the students, teachers and researchers in the area of telecommunication.
