Global cognitive radio based communication systems: Space-time communications
نویسندگان
چکیده
In an effort to find ways of meeting the increasing demand for spectrum, researchers tried observing the actual utilization (in licensed band) over the temporal and spatial dimensions. Surprisingly FCC found that actual utilization over certain time and spatial location was as low as 15%. Capitalizing on this observation, Joseph Mitola III proposed the idea of cognitive radio for dynamic spectrum access [1]. In section 2, details of cognitive radio as “currently understood” are explained.

Spectrum Assignment in Cognitive Radio Networks Using Fuzzy Logic Empowered Ants
The prevalent communications networks suffer from lack of spectrum and spectrum inefficiency. This has motivated researchers to develop cognitive radio (CR) as a smart and dynamic radio access promised solution. A major challenge to this new technology is how to make fair assignment of available spectrum to unlicensed users, particularly for smart grids communication. This paper introduces an i...

متن کاملInterference mitigation for cognitive radio MIMO systems based on practical precoding
In this paper, we propose two subspace-projection-based precoding schemes, namely, full-projection (FP)and partial-projection (PP)-based precoding, for a cognitive radio multiple-input multiple-output (CR-MIMO) network to mitigate its interference to a primary time-division-duplexing (TDD) system. The proposed precoding schemes are capable of estimating interference channels between CR and prim...
