Successive Decode-and-Forward Relaying With Privacy-Aware Interference Suppression

open access: yesIEEE Access, 2020
Successive relaying holds the promise of achieving spatial diversity gain for single-antenna users while recovering the multiplexing loss due to the half-duplex relaying in B5G/6G.

Novel half-duplex relay strategy and its resource allocation

open access: yesTongxin xuebao, 2009
Conventional time-division half-duplex relay strategies based on amplify-and-forward or decode-and-forward strategy could relieve relay nodes from full-duplex requirement but lead to degraded spectrum efficiency.

A decode and forward protocol for two-stage Gaussian relay networks

open access: yes, 2012
—We propose a multihopping decode and forward relaying protocol for two-stage Gaussian relay networks with half-duplex nodes. We analytically show that the achievable rates in suitably defined strong and weak interference regimes are close to the cut-set

A Novel Multi-Layer Cooperative Decode and Forward Scheme

open access: yesVTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009
Decode-and-forward (DF) is one of the most popular approach to transmit information over a cooperative relay channel. In DF, information coming from different sources is simply combined regardless of their respective link qualities, and thus DF is not optimized for any propagation conditions.

Relay Location Optimization for Full-Duplex Decode-and-Forward Relaying

open access: yes, 2013
In this paper, we investigate the optimum relay location for full-duplex decode-and-forward (DF) relaying systems. The outage probability is adopted as the optimization criterion and a relay location optimization problem is formulated.
