Spectral-Efficient Quadrature Spatial Modulation Cooperative Amplify and Forward Spectrum-Sharing Systems
Spectral-Efficient Quadrature Spatial Modulation Cooperative Amplify and Forward SpectrumSharing Systems Abstract: Quadrature spatial modulation (QSM) is a recent multiple-input-multiple-output (MIMO) digital transmission paradigm. Combining QSM with cooperative relaying in spectrum-sharing systems improves the overall spectral efficiency and enhances the communication reliability. In this paper, we study the performance of QSM-MIMO amplify-and-forward (AF) cooperative relaying spectrum-sharing […]
