Amplify-and-Forward Capacity with Transmit Beamforming for MIMO Multiple-Relay Channels
In this paper, we consider a MIMO wireless relay network where communication between a source and a destination node is assisted by multiple relay nodes using the Amplifyand-Forwar...

Low complexity MIMO scheduling with channel decomposition using capacity upperbound
Abstract In multiuser MIMO systems, the base station schedules transmissions to a group of users simultaneously. Since the data transmitted to each user are different, in order to ...

Optical Wireless MIMO (OMIMO) with Backward Spatial Filter (BSF) in Diffuse Channels
Abstract— In this paper, we propose optical wireless multipleinput multiple-output (OMIMO) with backward spatial filter (BSF) in diffuse channels. In the proposed system BSF is ...
