Enhanced Feedback Mechanisms for Resource-Efficient Incremental Redundancy
Mustafa Cemil Coşkun, Ahmed Elkelesh, Avijit Mandal +1
Incremental redundancy (IR) can reduce error rates by spreading coded bits across multiple transmission attempts. However, conventional stop-and-wait operation with coarse feedback…
Precoding-Oriented CSI Feedback Design with Mutual Information Regularized VQ-VAE
Xi Chen, Homa Esfahanizadeh, Foad Sohrabi
Efficient channel state information (CSI) compression at the user equipment plays a key role in enabling accurate channel reconstruction and precoder design in massive multiple-inp…
Multi-level Reliability Interface for Semantic Communications over Wireless Networks
Tze-Yang Tung, Homa Esfahanizadeh, Jinfeng Du +1
Semantic communication, when examined through the lens of joint source-channel coding (JSCC), maps source messages directly into channel input symbols, where the measure of success…
Successive Refinement in Large-Scale Computation: Advancing Model Inference Applications
Homa Esfahanizadeh, Alejandro Cohen, Shlomo Shamai +1
Modern computationally-intensive applications often operate under time constraints, necessitating acceleration methods and distribution of computational workloads across multiple e…
A Non-Asymptotic Analysis of Mismatched Guesswork
Alexander Mariona, Homa Esfahanizadeh, Rafael G. L. D'Oliveira +1
The problem of mismatched guesswork considers the additional cost incurred by using a guessing function which is optimal for a distribution when the random variable to be guess…
InfoShape: Task-Based Neural Data Shaping via Mutual Information
Homa Esfahanizadeh, William Wu, Manya Ghobadi +2
The use of mutual information as a tool in private data sharing has remained an open challenge due to the difficulty of its estimation in practice. In this paper, we propose InfoSh…

Ultra-reliability and low-latency are pivotal requirements of the new 6th generation of communication systems (xURLLC). Over the past years, to increase throughput, adaptive active…
A Unified Spatially Coupled Code Design: Threshold, Cycles, and Locality
Homa Esfahanizadeh, Eshed Ram, Yuval Cassuto +1
Spatially-Coupled (SC)-LDPC codes are known to have outstanding error-correction performance and low decoding latency. Whereas previous works on LDPC and SC-LDPC codes mostly take…
Stream Distributed Coded Computing
Alejandro Cohen, Guillaume Thiran, Homa Esfahanizadeh +1
The emerging large-scale and data-hungry algorithms require the computations to be delegated from a central server to several worker nodes. One major challenge in the distributed c…
Spatially Coupled Codes with Sub-Block Locality: Joint Finite Length-Asymptotic Design Approach
Homa Esfahanizadeh, Eshed Ram, Yuval Cassuto +1
SC-LDPC codes with sub-block locality can be decoded locally at the level of sub-blocks that are much smaller than the full code block, thus providing fast access to the coded info…
