Sum-Rate Maximization for Two-Way Active Channels
In this thesis, the term passive channel refers to the conventional parallel wireless channel model, where there is no control over the gain of each individual subchannel. We define an active channel as a parallel channel where by injecting power into the subchannels, somewhere between a transmitter and a receiver, the gain of the subchannels are adjusted. We herein study the problem of joint p...
متن کاملSum-Rate Maximization with Minimum Power Consumption for MIMO DF Two-Way Relaying: Part I - Relay Optimization
The problem of power allocation is studied for a multiple-input multiple-output (MIMO) decode-and-forward (DF) two-way relaying system consisting of two source nodes and one relay. It is shown that achieving maximum sum-rate in such a system does not necessarily demand the consumption of all available power at the relay. Instead, the maximum sum-rate can be achieved through efficient power allo...
متن کاملSum-Rate Maximization With Minimum Power Consumption for MIMO DF Two-Way Relaying— Part II: Network Optimization
In Part II of this two-part paper, a sum-rate-maximizing power allocation with minimum power consumption is derived for multiple-input multiple-output (MIMO) decode-and-forward (DF) two-way relaying (TWR) in a network optimization scenario. In this scenario, the relay and the source nodes jointly optimize their power allocation strategies to achieve network optimality. Unlike the relay optimiza...
متن کاملMaximizing Sum-Rate for Multi-User Two-Way Relaying Networks with ANC Protocol
In this paper we study the resource allocation problem for an OFDMA based cooperative two-way relaying (TWR) network. We focus on amplify and forward (AF) analog network coding (ANC) protocol. An optimization problem for two basic resources namely, sub-carrier and power is formulated for multi-user TWR networks. A joint optimal optimization problem is investigated and two-step low complexity su...
متن کاملPerformance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward
In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...
