Smart relaying for selection combining based decode-and-forward cooperative networks

open access: yes, 2014
This letter proposes three smart relaying strategies, including power allocation, continuous power control, and discrete power control strategies, to mitigate the error propagation problem for single-relay decode-and-forward cooperative networks using ...

Successive Decode-and-Forward Relaying with Reconfigurable Intelligent Surfaces

open access: yesICC 2022 - IEEE International Conference on Communications, 2022
The key advantage of successive relaying (SR) networks is their ability to mimic the full-duplex (FD) operation with half-duplex (HD) relays. However, the main challenge that comes with such schemes is the associated inter-relay interference (IRI). In this work, we propose a reconfigurable intelligent surface (RIS)-enhanced SR network, where one RIS is

Differential space-time shift-keying aided successive-relaying-assisted decode-and-forward cooperative multiuser CDMA

open access: yes, 2013
A Differential Space-Time Shift Keying (DSTSK) aided and successive relaying assisted multi-user Decode-and-Forward (DF) cooperative system is proposed. We employ low-complexity non-coherent detection, which does not require any channel state information,

Cognitive decode-and-forward relaying with successive interference cancelation

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
In this work, we study the cognitive decode-and-forward (DF) relaying, where a primary user (PU) communicates with an access point (AP), and in the same geographical region, a secondary source (SS) communicates to a secondary destination (SD) with ...

Achievable rates for the restricted half-duplex two-way relay channel under a partial-decode-and-forward protocol

open access: yes, 2008
In this paper, we state a new achievable rate region for the two-phase two-way relay channel with a half-duplex relay node. The new region is obtained using a partial-decode-and-forward protocol, which is a superposition of both, decode-and-forward and ...

Successive-relaying-aided decode-and-forward coherent versus noncoherent cooperative multicarrier space–time shift keying

open access: yes, 2013
—Successive-relaying-aided (SR) cooperative multi-carrier (MC) space–time shift keying (STSK) is proposed for frequency-selective channels. We invoke SR to mitigate the typical 50% throughput loss of conventional half-duplex relaying schemes and MC code ...

Performance Analysis of Cooperative Quadrature Spatial Modulation System With Hybrid Decode-Amplify-Forward Relaying Protocol

open access: yesIEEE Access
This paper introduces the cooperative quadrature spatial modulation (CQSM) system with hybrid decode-amplify-forward (HDAF) relaying protocol. Compered with the traditional CQSM system which only uses amplify-and-forward (AF) protocol and decode-and ...
