Rate Control for Wireless-Powered Communication Network with Reliability and Delay Constraints
Onel L. Alcaraz López, Hirley Alves, Richard Demo Souza +2
We consider a two-phase Wireless-Powered Communication Network under Nakagami-m fading, where a wireless energy transfer process first powers a sensor node that then uses such ener…
A Throughput and Energy Efficiency Scheme for Unlicensed Massive Machine Type Communications
Iran Ramezanipour, Hirley Alves, Pedro J. H. Nardelli +1
In this paper the throughput and energy efficiency of an unlicensed machine type communications network is studied. If an outage event happens in the network, there is a possibilit…
In-Band Pilot Overhead in Ultra-Reliable Low Latency Decode and Forward Relaying
Parisa Nouri, Hirley Alves, Richard Demo Souza +1
In URLLC the performance of short message communications highly depends on the training sequence length due to the stringent latency and reliability requirements. In this paper, we…
Performance of Non-orthogonal Multiple Access under Finite Blocklength
Endrit Dosit, Mohammad Shehab, Hirley Alves +1
In this paper, we present a finite-block-length comparison between the orthogonal multiple access (OMA) scheme and the non-orthogonal multiple access (NOMA) for the uplink channel.…
On the Statistics of the Ratio of Non-Constrained Arbitrary α-μ Random Variables: a General Framework and Applications
J. D. Vega Sánchez, D. P. Moya Osorio, E. E. Benitez Olivo +3
In this paper, we derive closed-form exact expressions for the main statistics of the ratio of squared alpha-mu random variables, which are of interest in many scenarios for future…
