recommendations! Published in 2018 at "IEEE Wireless Communications Letters"

DOI: 10.1109/lwc.2017.2777857

Abstract: This letter analyzes and compares the performance of full-duplex relaying (FDR) and half-duplex relaying (HDR) for ultrareliable short-packet communications. Specifically, we derive both approximate and asymptotic closed-form expressions of the block error rate (BLER) for… read more here.
