An Adaptive Transmission Strategy Based on Success Rate of Transmission
Zheng Zhou · Radio and communications technology · 2011
We consider a cognitive radio(CR) network that makes opportunistic access to a spectrum licensed to the primary users.Under the needs of sensing time,it is critical issue for CR user to track the status of the primary user,thus reducing the interference to the primary user,and maximizing the data throughput at the same time.For this question,an adaptive transmission strategy(ATSSR) based on success rate of transmission is proposed carrying out spectrum Sensing and data transmission on an adaptive-frame basis.Simulation results show that compared with the literature[2],ATS-SR in the case of no loss in throughput can reduce the interference to primary user.
