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...

To minimize total transmit power in a system while guaranteeing the outage probability at the same time in a cooperative system, we propose and analyse two threshold-based hybrid relay selection and power allocation schemes for a threenode cooperative relaying system. They are designated as: the hybrid amplify-direct-forward relaying (HADF) and incremental hybrid decode-direct-forward relaying ...

“Amplify and Forward” and “Decode and Forward” are the two main relaying functions that have been proposed since the advent of cooperative communication. “Soft Decode and Forward” is a recently introduced relaying principle that is to combine the benefits of the classical two relaying algorithms. In this work, we thoroughly investigate soft relaying algorithms when convolutional or turbo codes ...

This paper considers a full-duplex two-way relaying (FD-TWR) system, where two terminals transmit and receive simultaneously with the help of a full-duplex relay node. We propose the transmission scheme for decode-and-forward (DF) protocol using the differential binary phase-shift keying (DBPSK) modulation to analyse the bit error ratio (BER), which do not need the channel state information (CS...

In this paper, an exact closed-form bit error rate expression for M -PSK is presented for multi-hop Decode-and-Forward Relaying (MDFR) scheme, in which selection combining technique is employed at each node. We have shown that the proposed protocol offers remarkable diversity advantage over direct transmission as well as the conventional decode-and-forward relaying (CDFR) scheme. Simulations ar...
