IRSA-based Random Access over the Gaussian Channel
Velio Tralli, Enrico Paolini
A framework for the analysis of synchronous grant-free massive multiple access schemes based on the irregular repetition slotted ALOHA (IRSA) protocol and operating over the Gaussi…
Irregular Repetition Slotted ALOHA in an Information-Theoretic Setting
Enrico Paolini, Lorenzo Valentini, Velio Tralli +1
An information-theoretic approach to irregular repetition slotted ALOHA (IRSA) is proposed. In contrast with previous works, in which IRSA analysis is conducted only based on quant…
A Low Complexity Space-Frequency Multiuser Scheduling Algorithm
Ana I. Pérez-Neira, Pol Henarejos, Velio Tralli +1
This work presents a resource allocation algorithm in K-user, M-subcarrier and NT-antenna systems for on-line scheduling. To exploit temporal diversity and to reduce complexity, th…
Evolution of Spatial and Multicarrier Scheduling: Towards Multi-cell Scenario
Pol Henarejos, Ana Perez-Neira, Velio Tralli +3
OFDMA systems are considered as the promising multiple access scheme of next generation multi-cellular wireless systems. In order to ensure the optimum usage of radio resources, OF…
Log-concavity property of the error probability with application to local bounds for wireless communications
Andrea Conti, Dmitry Panchenko, Sergiy Sidenko +1
A clear understanding the behavior of the error probability (EP) as a function of signal-to-noise ratio (SNR) and other system parameters is fundamental for assessing the design of…
On Punctured Pragmatic Space-Time Codes in Block Fading Channel
Samuele Bandi, Luca Stabellini, Andrea Conti +1
This paper considers the use of punctured convolutional codes to obtain pragmatic space-time trellis codes over block-fading channel. We show that good performance can be achieved…
