Application of Phase Shift in Coherent Multi-Relay MIMO Communications
—In this paper we propose a new low feedback and low complexity scheme that adjusts the phases at the relays, thus allowing for the coherent combining of signals from multiple re...

Evaluation of Outage Restricted Distributed MIMO Multi-Hop Networks by the Improved Approximative Power Allocation
—The concept of Virtual Antenna Array (VAA) is a promising approach to apply MIMO concepts in relaying systems. In order to fulfill a given Quality-of-Service (QoS) requirement ...

Beamforming with Finite Rate Feedback for LOS MIMO Downlink Channels
— We consider a MIMO line of sight (LOS) broadcast channel where each user has perfect knowledge of its own channel and feeds back ‘quantized’ channel information to the tran...

Limited Feedback Precoding in Realistic MIMO Channel Conditions
— MIMO system design for real applications requires that factors such as channel estimation errors, feedback quantisation and realistic channel responses be taken into account. L...
