Abstract
Cognitive radio (CR) is one of the most intensively researched paradigms in recent wireless communication systems. The great deal of attention that CR has attracted can be ascribed to its demonstrated capability to increase spectrum efficiency and overall network capacity through interference-free spectrum sharing among several wireless communication systems. CR provides intelligence to wireless networks, enabling users to access multiple air interfaces and select the most appropriate alternative under varying communication needs and operation conditions. The potential benefits of CR have not gone unnoticed to many wireless communication systems, which nowadays have effectively benefited M.

from the adoption of CR techniques and operating principles. This chapter provides an overview on the introduction of CR principles into two prominent wireless communication systems, namely, mobile and satellite communication networks. A detailed discussion is provided on the background and motivation for the adoption of the CR technology and how CR techniques ha
