Codebook design for distributed relay beamforming system
In FDD amplify-and-forward distributed relay network, codebook techniques are utilized to feedback quantized CSI with limited cost. First, this thesis focuses on the phaseonly codebook and with-power-control codebook design methods under individual relay power constraints. Phase-only codebooks can …

Cooperative relay beamforming design for multi-cluster relay interference networks
… a multi-cluster amplified-and-forward (AF) relay interference network and design relay beam matrix for each cluster to maximize the minimum signal-to-interference-and-noise ratio (SINR) at destinations subject to the relay power budget within each cluster. Both single and multiple …

Joint relay beamforming and transceiver processing in multiuser relay network
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 (S-D) pairs intend to communicate with the help of multiple distributed amplify-and-forward (AF) relays. A …

Asynchronous bi-directional relay-assisted communication networks
We consider an asynchronous bi-directional relay network, consisting of two singleantenna transceivers and multiple single-antenna relays, where the transceiver-relay paths are subject to different relaying and/or propagation delays. Such a network can be viewed as a multipath channel which can …

Jointly optimal pre- and post-channel equalization and distributed beamforming in asynchronous bi-directional relay networks
We consider an asynchronous two-way relay network, consisting of two transceivers and multiple relays, where due to the propagation delays of different transceiver-relay paths being different, inter-symbol- interference (ISI) exists at both transceivers. In this work, pre- and post-channel …

Multi-antenna relay network beamforming design for multiuser peer-to-peer communications.
… this work, we consider a multi-user peer-to-peer relay network with multiple multiantenna relays which employ amplify-and-forward relaying protocol. Assuming distributed relay beamforming strategy, we investigate the design of each relay processing matrix to minimize the per-antenna relay power …

Power-optimal MIMO two-way relay networks
In this dissertation, we study MIMO two-way relay networks consisting of singleantenna users which wish to exchange information with the help of multiple multiantenna relays. The problem we aim to solve is to minimize the total transmit power consumed in the entire network while certain …

Resource allocation and secure communication design in simultaneous wireless information and power transfer systems
… network in which the amplify-and-forward (AF) relay protocol is employed at the multi-antenna relay. A power splitting (PS) receiver architecture is utilized at each destination node to implement energy harvesting (EH) and information decoding (ID) simultaneously. The aim of this chapter is to …
