Information Leakage in Index Coding With Sensitive and Non-Sensitive Messages

Yucheng Liu, Lawrence Ong, Phee Lep Yeoh +3

Information leakage to a guessing adversary in index coding is studied, where some messages in the system are sensitive and others are not. The non-sensitive messages can be used b…

Information Leakage in Index Coding

Yucheng Liu, Lawrence Ong, Phee Lep Yeoh +3

We study the information leakage to a guessing adversary in index coding with a general message distribution. Under both vanishing-error and zero-error decoding assumptions, we dev…

Information Leakage in Zero-Error Source Coding: A Graph-Theoretic Perspective

Yucheng Liu, Lawrence Ong, Sarah Johnson +3

We study the information leakage to a guessing adversary in zero-error source coding. The source coding problem is defined by a confusion graph capturing the distinguishability bet…

Clustering-based Joint Channel Estimation and Signal Detection for Grant-free NOMA

Ayoob Salari, Mahyar Shirvanimoghaddam, Muhammad Basit Shahab +2

We propose a joint channel estimation and signal detection technique for the uplink non-orthogonal multiple access using an unsupervised clustering approach. We apply the Gaussian…

Grant-free Non-orthogonal Multiple Access for IoT: A Survey

Muhammad Basit Shahab, Rana Abbas, Mahyar Shirvanimoghaddam +1

Massive machine-type communications (mMTC) is one of the main three focus areas in the 5th generation (5G) of mobile standards to enable connectivity of a massive number of interne…

Protograph LDPC Code Design for Asynchronous Random Access

Federico Clazzer, Balazs Matuz, Sachini Jayasooriya +2

This work addresses the physical layer channel code design for an uncoordinated, frame- and slot-asynchronous random access protocol. Starting from the observation that collisions…
