Properly designed precoders can significantly improve the spectral efficiency of multiple-
input multiple-output (MIMO) relay systems. In this paper, we investigate joint source and …

In this correspondence, we study the problem of joint receive and transmit beamforming for a
wireless network consisting of a transmitter, a receiver, and a relay node. The relay node is …

In this paper, we consider the problem of precoding design for amplify-and-forward (AF)
relay network with imperfect channel state information (CSI). We find a general rank …

We study the problem of sum-rate maximization, under a total transmit power budget, for an
asynchronous single-carrier bidirectional (two-way) network. The network consists of two …

In this thesis, we focus on joint relay beamforming and transceiver processing in multiuser
relay network. First of all, we consider the scenario in which multiple source-to-destination …

In this thesis, we consider a single-carrier asynchronous two-way relay network, where the
relays employ amplify-and-forward (AF) signaling in a multiple access broadcast channel …

The ever shrinking cell sizes to accommodate more users make the performance of wireless
cellular networks interference limited. To mitigate inter-cell interference in downlink …

Abstract<? Pub Inc> In wireless communications, channel estimation is necessary for
coherent symbol detection. This thesis considers a network which consists of two …
