This paper proposes a deep learning-based channel estimation method for multiple-input multiple-output (MIMO) systems in spatially correlated channels. To reduce the pilot overhead of pilot symbol-assisted channel estimation, the proposed method util

Abstract We consider the deployment of a large-scale circular layout-distributed antenna system. To maximize energy efficiency, we define the optimization problem with the approximated analysis and find the number of deployed antennas as a closed-for

We propose a time synchronization method which is applicable to both offset quadrature amplitude modulation based filter-bank multicarrier (FBMC-OQAM) system and quadrature amplitude modulation based filter-bank multicarrier (FBMC-QAM) system. Based

Under multipath fading channels, maximum likelihood detection of multiple-input multiple-output filter-bank multicarrier-quadrature amplitude modulation (MIMO FBMC-QAM) system suffers from the performance degradation due to the residual interference.
