POLARIZED DIVERSITY COMPACT PLANAR MIMO ANTENNA FOR WIRELESS ACCESS POINT APPLICATIONS

open access: yesProgress In Electromagnetics Research C, 2019
In this paper, a wideband polarization diversity multi-input multioutput (MIMO) antenna system is proposed. The structure of the proposed antenna consists of four wideband coplanar waveguide (CPW)-fed monopole antennas with a common ground plane and radiated element.

Linear Precoding for the MIMO Multiple Access Channel with Finite Alphabet Inputs and Statistical CSI [PDF]

open access: yes, 2014
In this paper, we investigate the design of linear precoders for the multiple-input multiple-output (MIMO) multiple access channel (MAC). We assume that statistical channel state information (CSI) is available at the transmitters and consider the problem
