Codes and Games for Dynamic Spectrum Access
Cognitive radio is an emerging wireless communications paradigm in which either the network or the wireless node itself intelligently adapts particular transmission or reception parameters by sensing the environment. The goals of adaptation include maximizing spectral efficiency, minimizing interference to other cognitive radios, coexistence of licensed and unlicensed band communications, battery energy efficiency, etc. The environmental parameters that are continually sensed for adaptation include occupied radio frequency bands, user traffic, network state, etc. One promising technology that enables the implementation of a cognitive radio network is software-defined radio. The underlying theoretical principles for cognition are broadly based on signal-processing and machine-learning.
