Advanced Frame Structures for Hybrid Spectrum Access Strategy in Cognitive Radio Communication Systems

Abstract

In this letter, we have exploited a novel hybrid-cumimproved spectrum access technique for significant improvement in the throughput and data-loss rate. This proposed technique comprises of hybrid spectrum access and improved frame structure strategies of the cognitive radio communication system. Also, the closed-form expressions for throughput and data-loss of these approaches are derived. Moreover, the proposed approaches are validated numerically as well as with reported literature.
