最小信道检测开销的协作频谱感知算法
Cooperative spectrum sensing algorithm based on minimum detecting overhead
摘要
Abstract
In the limited resource wireless cognitive radio networks,the application of the cooperative spectrum sensing technique improves system performance,but also results in the increase of channel detecting overhead.In this context,selecting appropriate system parameters can effectively minimize the detecting overhead.After analyzing the models of single-user and multi-user spectrum sensing systems based on energy detection,we proposed a cooperative spectrum sensing algorithm based on minimum detecting overhead.The main ideas of the algorithm and implementation steps are given.In addition,we have derived a detecting overhead formula,and theoretically proved the existence of the minimum of detection overhead.Furthermore,simulation results verify effectiveness of system parameter optimization and reliability of the algorithm.关键词
