Distributed interference and data buffer management for cognitive radio

Bayo Moya, Alberto January 2010 (has links)
Future wireless communications are focused on develop new paradigms of spectrum reuse, i.e. cognitive radio, where radio frequencies can be taken into used if no other use is detected. In this way, these systems need mechanisms for interference control. In this work we study the use of a distributed system based on cognitive radio. Scheduling transmitters and data rate optimization algorithms have been implemented in order to balance the secondary user transmissions and maximize the data rate transmission. Radio sensors are used to monitor the interference levels generated by the different transmitters. The system model has been implemented in MATLAB and analyzes its behaviour through several simulations.
