An Optimized Algorithm for Recourse Allocation Based on Cognitive Radios
Zou Jing-yuan · Journal of Hangzhou Dianzi University · 2009
Cognitive radio(CR) can increase the utilization rate of the spectrum by dynamically using the spectrum hole of primary users.The optimized algorithm can find the optimal set of collaborative nodes for resource allocation,and at the same time avoid the interference to primary users.Simulation demonstrates that this scheme greatly increases the mean throughput of cognitive network as well as the transmission capacity of each sub-carrier.
