Joint Underlay/Interweave Spectrum Access Scheme with Reduced Data Loss
Indu Bala · Journal of Emerging Technologies and Innovative Research · 2019
In this paper, joint Underlay/interweave power control scheme is discussed to enhance secondary user’s throughput and to reduce data loss during collision in a typical spectrum sharing environment. To do so, the conventional data frame structure has been modified by incorporating two sensing slots to avoid sensing results ambiguity. It is shown that proposed scheme has a potential to improve the unlicensed user’s throughput and reduce data loss significantly. The numerical results are presented to prove the efficiency of the proposed scheme. Moreover, the performance of proposed scheme is also compared with the state of art spectrum access schemes to validate the results.
