Type-Based Unsourced Multiple Access Over Fading Channels in Distributed MIMO With Application to Multi-Target Localization
Kaan Okumus, Khac-Hoang Ngo, Giuseppe Durisi +2
We consider the problem of type estimation over unsourced multiple access fading channels in distributed multiple-input multiple-output (D-MIMO) systems. Unlike classical unsourced…
Improving 3D Cellular Positioning Integrity with Bayesian RAIM
Liqin Ding, Gonzalo Seco-Granados, Hyowon Kim +4
Ensuring positioning integrity amid faulty measurements is crucial for safety-critical applications, making receiver autonomous integrity monitoring (RAIM) indispensable. This pape…
Type-Based Unsourced Multiple Access over Fading Channels with Cell-Free Massive MIMO
Kaan Okumus, Khac-Hoang Ngo, Giuseppe Durisi +1
Type-based unsourced multiple access (TUMA) is a recently proposed framework for type-based estimation in massive uncoordinated access networks. We extend the existing design of TU…
Undetected Error Probability in the Short Blocklength Regime: Approaching Finite-Blocklength Bounds with Polar Codes
Alexander Sauter, A. Oguz Kislal, Giuseppe Durisi +3
We analyze the trade-off between the undetected error probability (i.e., the probability that the channel decoder outputs an erroneous message without detecting the error) and the…
Is Synchronization a Bottleneck for Pilot-Assisted URLLC Links?
A. Oguz Kislal, Madhavi Rajiv, Giuseppe Durisi +2
We propose a framework to evaluate the so-called random-coding union bound with parameter (RCUs) on the achievable error probability in the finite-blocklength regime for a pilo…
Type-Based Unsourced Multiple Access
Khac-Hoang Ngo, Deekshith Pathayappilly Krishnan, Kaan Okumus +2
We generalize the type-based multiple access framework proposed by Mergen and Tong (2006) to the case of unsourced multiple access. In the proposed framework, each device tracks th…
