Future communications systems will have to integrate multiple radio technologies in order to support a large number of wireless standards (cellular technology, WMAN, WLAN and WPAN). The concept of Software-Defined Radio (SDR) in which a common hardware platform is used to cover any communication channel in a wide frequency spectrum with any modulation and bandwidth, supports this trend (Mitola, 1995; Haykin, 2005). In light of the functional flexibility and platform programmability requirements, one of the major challenges of SDR clearly resides in energy consumption. Besides the energy constraints, spectrum is becoming also a major resource bottleneck because of the steady increase in the number of wireless users and applications. The accelerated deployment of broadband personal communication and the continuously increasing demand for higher data rates will crow the limited and precious frequency spectrum.
