Hybrid Protocols for Relay-Assisted Non-Orthogonal Multiple Access in Power Line Communications
We study the outage probability performance of hybrid protocols in relay-assisted, non-orthogonal multiple access (NOMA)-based power line communication. In particular, we consider two networks with source, relay and destination nodes, namely, cooperative

Joint Channel-Network Coding for the Gaussian Two-Way Two-Relay Network
New aspects arise when generalizing two-way relay network with one relay to two-way relay network with multiple relays. To study the essential features of the two-way multiple-relay network, we focus on the case of two relays in our work. The problem of

Covert Communications in a Hybrid DF/AF Relay System. [PDF]
In this paper, we study covert communications in a hybrid decode-and-forward (DF)/ amplify-and-forward (AF) relay system. The considered relay in normal operation forwards messages from a source node to a destination node in either DF or AF mode on ...

Cooperative Detection for Primary User in Cognitive Radio Networks
We propose two novel cooperative detection schemes based on the AF (Amplify and Forward) and DF (Decode and Forward) protocols to achieve spatial diversity gains for cognitive radio networks, which are referred to as the AF-CDS, (AF-based Cooperative ...

Multilevel Coding for the Full-Duplex Decode-Compress-Forward Relay Channel
The Decode-Compress-Forward (DCF) is a generalization of Decode-Forward (DF) and Compress-Forward (CF). This paper investigates conditions under which DCF offers gains over DF and CF, addresses the problem of coded modulation for DCF, and evaluates the ...

Cooperative Transmission and Performance Analysis Based on Superposition Coding [PDF]
In the traditional three-node cooperative communication model,relay nodes forward data for free for source nodes,which reduces the spectral efficiency.To address the problem,this paper proposes a cooperative transmission mode based on the Decode-and ...
