Multi-Hop Relaying: An End-to-End Delay Analysis

Two Average Symbol Error Rate Expressions for AFwRRD and AFwRTD Systems over Rayleigh Fading channels

“…In general, a dual-hop and multi-hop relay systems can be used to extend the network coverage and to enhance throughput owing to shorter hops [1][2][3][4][5][6][7][8][9][10][11][12]. It is also guarantee the network connectivity to locations of which the general single-hop network cannot connect [1].…”

“…The performance improvement in a dual-hop and a multi-hop system can also be achieved via spatial diversity gains [1][2][3]. For these reasons, many researchers have widely discussed for their performance [1][2][3][4][5][6][7][8][9][10][11][12].…”

“…For dual-hop adaptive decode-and-forward (DF) schemes with burst transmission, approximated error rates were derived in [4]. The multi-hop AF relay systems have been analyzed, with or without cooperative diversity [5][6][7][8][9][10][11][12]. The authors in [5] and [6] proposed a signal-to-noise ratio (SNR) upper bound by using mini-mum SNR of all hops.…”

“…Note that in [8], multi-hop relay system is divided into two sub-systems. Recently, the authors in [9] derived the transmission latency of multi-hops DF and AF. However, these works are all based on a single-branch multi-hop system without cooperative diversity reception.…”

Finite Blocklength Performance of Cooperative Multi-Terminal Wireless Industrial Networks

“…A closed-form expression for the outage probability is provided in [8]. The authors of [9] investigate the impact on the transmission delay when using relaying compared to direct transmissions, i. e., under which conditions relaying improves the end-to-end transmission delay. A latency analysis is derived under the assumption of a Gaussian channel, not including the effects of a fading channel.…”
