Buffer-Aided Max-Link Relay Selection for Two-Way Cooperative Multi-Antenna Systems
Flavio L. Duarte, Rodrigo C. de Lamare · 2019
In this paper, we investigate relay-selection techniques for two-way cooperative multi-antenna systems, where two terminals simultaneously transmit to each other with the help of relays. In particular, we present a novel two-way relay selection technique based on the selection of the best link, making use of buffers and physical-layer network coding (PLNC), that is named Two-Way Max-Link (TW-Max-Link). We compare the proposed TW-Max-Link to the existing approaches, in terms of pairwise error probability and bit error rate. Simulations are then employed to evaluate the performance of the proposed and existing techniques.
