Abstract: This paper proposes the efficient downlink channel state information (CSI) feedback scheme for reconfigurable intelligent surface (RIS) assisted multi-user multi-input multi-output (MU-MIMO) wireless communication systems. RIS is the state-of-the-art technology that is extensively researched as… read more here.

DOI: 10.1109/tpel.2017.2690361
Abstract: It is mandatory to keep the total harmonic distortion in the output of most inverters below the limits prescribed by different international standards. The harmonic distortions caused due to nonlinear loads may not get corrected… read more here.
