Multipair Two-Way DF Relaying With Cell-Free Massive MIMO
IEEE Open Journal of the Communications Society, 2021 We consider a two-way half-duplex decode-and-forward (DF) relaying system with multiple pairs of single-antenna users assisted by a cell-free (CF) massive multiple-input multiple-output (mMIMO) architecture with multiple-antenna access points (APs ...

Smart Decode-and-Forward Relaying with Polar Codes [PDF]
IEEE Wireless Communications Letters, 2014 Polar codes have recently been proven to be capacity achieving for the physically degraded relay channel and relevant coding schemes have been proposed in the literature. In this paper, we deal with the design of polar codes in decode-and-forward relaying and prove that the selective transmission of the relay to the destination, based on the decision ...

Robust Transceiver Design for IRS-Assisted Cascaded MIMO Communication Systems
Sensors, 2022 Intelligent reconfigurable surfaces (IRSs) have gained much attention due to their passive behavior that can be a successor to relays in many applications. However, traditional relay systems might still be a perfect choice when reliability and throughput

Cascade decode-and-forward : spatial diversity reuse in sensor networks [PDF]
, 2016 In this paper, we consider a wireless sensor network that involves sensory data hoping through multiple wireless relays to reach a central collection hub. In particular we improve the decode-and-forward cooperative relaying scheme.
