Spectrum Sensing Scheme Measuring Packet Lengths of Interfering Systems for Dynamic Spectrum Sharing
IEEE Access, 2021 For the dynamic spectrum sharing (DSS), this paper proposes a spectrum sensing scheme that measures packet lengths of interfering systems. DSS requires spectrum sensing techniques to measure a length of time for which the interfering systems use a ...

Market Based Approaches for Dynamic Spectrum Assignment [PDF]
, 2009 —Much of the technical literature on spectrum sharing has been on developing technologies and systems for non-cooperative) opportunistic use. In this paper, we situate this approach to secondary spectrum use in a broader context, one that includes ...

Protection regions for dynamic spectrum sharing
Electronics Letters, 2010 It is shown that existing approximation-based techniques for dynamic spectrum sharing (involving randomly placed unlicensed devices) cannot guarantee primary system protection. For the first time, an analysis is presented that compares the approximate and exact protection criteria.

Decentralized Dynamic Rate and Channel Selection Over a Shared Spectrum [PDF]
IEEE Transactions on Communications, 2021 We consider the problem of distributed dynamic rate and channel selection in a multi-user network, in which each user selects a wireless channel and a modulation and coding scheme (corresponds to a transmission rate) in order to maximize the network throughput.

Coopetive spectrum trading - Creating endogenous spectrum holes [PDF]
, 2014 Dynamic spectrum access has been proposed to address the spectrum scarcity. Based on this access mode, secondary users are allowed to opportunistically operate when primary users are absent.
