— In this paper, we consider the transmission of a Gaussian source in a multi-relay cooperative network, where limited channel state feedback is combined with separate source and...
Coherent base station (BS) cooperative transmission provides high spectrum efficiency for cellular systems when channel state information (CSI) is perfectly known at the BSs. For...
This paper addresses the problem of beamforming (BF) design for orthogonal frequency division multiplexing (OFDM) based relay networks over frequency-selective channels. Both freq...
—This paper deals with distributed beamforming techniques for wireless networks with half-duplex amplify-andforward relays. Existing schemes optimize the beamforming weights base...
Most of the existing literature on cooperative relay networks has focused on frequency– nonselective channels or frequency–selective channels with multi–carrier transmission...
