认知无线电网络中非授权用户吞吐量性能研究
A study of the throughput performance of secondary users of the cognitive radio
摘要
Abstract
The paper studies the impacts of the idle time distribution and the packet collision probability constraint of primary users(PU)of cognitive radio networks on the throughput performance of secondary users(SU)based on the PU behaviour pattern investigation and the SU's throughput analysis. Meanwhile, this paper presents the SU optimum spectrum access strategy model and calculates the maximum throughout of SU under the condition of perfect sensing the PU idle time distribution. The simulation result was verified by comparing the theoretical result. The conclusion is that the maximum throughout of SU increases as the packet collision probability constraint increases.关键词
