Adaptive underlay cognitive radios with imperfect CSI and probabilistic interference constraints
2011 4th IEEE International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP)
Efficient design of cognitive radios requires secondary users implementing adaptive resource allocation schemes that exploit knowledge of the channel state information (CSI), and limit interference to the primary system. In this paper, stochastic resource allocation algorithms are developed for underlay cognitive radios to maximize the sum-rate of secondary users while adhering to "average power" and "probability of interference" constraints. The latter guarantee that during most of the timedoi:10.1109/camsap.2011.6135913 dblp:conf/camsap/MarquesLGR11 fatcat:zcgl2oowyfev7hsiewetzor6rm
