From Software Radio to Cognitive Radio

Software radio ideally provides the opportunity to communicate with
any radio communication standard by modifying only the software,
without any modification to hardware components. However, taking
into account the static behavior of current communications
protocols, the spectrum efficiency optimization, and flexibility,
the radio domain has become an important factor.
From this thinking appeared the cognitive radio paradigm. This
evolution is today inescapable in the modern radio communication
world. It provides an autonomous behavior to the equipment and
therefore the adaptation of communication parameters to better
match their needs.
This collective work provides engineers, researchers and radio
designers with the necessary information from mathematical analysis
and hardware architectures to design methodology and tools, running
platforms and standardization in order to understand this new
cognitive radio domain.
