A Novel Error Detection due to Joint CRC Aided Denoise-and-Forward Network Coding for Two-Way Relay Channels

by Yulun Cheng , Longxiang Yang
"... In wireless two-way (TW) relay channels, denoise-and-forward (DNF) network coding (NC) is a promising technique to achieve spectral efficiency. However, unsuccessful detection at relay severely deteriorates the diversity gain, as well as end-to-end pairwise error probability (PEP). To handle this i ..."

Relay Selection for MIMO and Massive MIMO Two-Way Relay Networks

by Jayamuni Mario, Shashindra S. Silva
"... Relay selection strategies help to improve spectral and energy efficiencies, to en-hance transmission robustness, or to reduce latency in multi-relay cooperative wire-less networks. Two novel relay selection strategies are proposed and analysed here for 1. Multiple-input multiple-output (MIMO) 2. Ma ..."
