On the Semantic Security in the General Bounded Storage Model: A New Proof
Mohammad Moltafet, Hamid R. Sadjadpour, Zouheir Rezki
In the bounded storage model introduced by Maurer, the adversary is computationally unbounded and has a bounded storage capacity. In this model, information-theoretic secrecy is gu…
An ML-assisted OTFS vs. OFDM adaptable modem
I. Zakir Ahmed, Hamid R. Sadjadpour
The Orthogonal-Time-Frequency-Space (OTFS) signaling is known to be resilient to doubly-dispersive channels, which impacts high mobility scenarios. On the other hand, the Orthogona…
An information-theoretic branch-and-prune algorithm for discrete phase optimization of RIS in massive MIMO
I. Zakir Ahmed, Hamid R. Sadjadpour, Shahram Yousefi
In this paper, we consider passive RIS-assisted multi-user communication between wireless nodes to improve the blocked line-of-sight (LOS) link performance. The wireless nodes are…
Constrained Resource Allocation Problems in Communications: An Information-assisted Approach
I. Zakir Ahmed, Hamid Sadjadpour, Shahram Yousefi
We consider a class of resource allocation problems given a set of unconditional constraints whose objective function satisfies Bellman's optimality principle. Such problems are ub…
Throughput Analysis of Decentralized Coded Content Caching in Cellular Networks
Mohsen Karimzadeh Kiskani, Hamid R. Sadjadpour
Decentralized coded content caching for next generation cellular networks is studied. The contents are linearly combined and cached in under-utilized caches of User Terminals (UTs)…
Fundamental Limits on Throughput Capacity in Information-Centric Network
Bita Azimdoost, Cedric Westphal, Hamid R. Sadjadpour
Wireless information-centric networks consider storage as one of the network primitives, and propose to cache data within the network in order to improve latency and reduce bandwid…
