Spectrum sharing for two-way relay networks
We consider a communication network consisting of two transceiver nodes, one relay node, and one receiving node. The relay enables a two-way communication between the two transceivers and meanwhile sends its own information to the receiving node. We study the problem of the power allocation to the …

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 …

Channel estimation in a two-way relay network
… symbol detection. This thesis considers a network which consists of two transceivers communicating with the help of a relay applying the amplify-and-forward (AF) relaying scheme. The training based channel estimation technique is applied to the proposed network where the numbers of the …

Power allocation in energy harvesting two-way relay systems
In this thesis, we consider two-way relaying in a wireless communication system with two transceivers and one relay node. In such a model, two scenarios are taken into account: a system with one energy harvesting (EH) relay node and a system with two EH transceivers and one EH relay node. Under …

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 …

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 …
