Semantic Split Inference for Remote Modulation Recognition
Samer Lahoud, Kinda Khawam
Remote automatic modulation recognition balances sensing-node complexity, reporting cost and accuracy. To address this trade-off, we propose channel-aware semantic split inference:…
HalifaxDT: A Wireless Digital Twin from Open Geospatial Data
Alexis Delplace, Xinyi Li, Samer Lahoud +1
Wireless digital twins can support site-specific analysis, planning, and experimentation for future wireless networks. However, constructing them at city scale remains challenging…
Semantic Communication for Distributed Spectrum Monitoring over Unreliable Links
Samer Lahoud, Kinda Khawam
Distributed spectrum monitoring relies on spatially separated receivers to infer the state of the radio environment. A central task is to determine how many emitters are active and…
Towards Realistic Waveform-Level IoT Network Simulation via IQ Mixing
Alexis Delplace, Samer Lahoud, Kinda Khawam +1
Most Internet of Things (IoT) network simulators are packet-level discrete-event systems in which physical-layer (PHY) behavior is approximated through analytical interference rule…
Design and Analysis of Chirp-Layered Superposition Coding for LoRa
Jingxiang Huang, Samer Lahoud
This paper investigates the design of chirp-layered superposition coding for LoRa, where an additional waveform is linearly superposed on a standard LoRa transmission with minimal…
Physical-Layer Analysis of LoRa Robustness in the Presence of Narrowband Interference
Jingxiang Huang, Samer Lahoud
With the rapid development of Internet of Things (IoT) technologies, the sub-GHz unlicensed spectrum is increasingly being shared by protocols such as Long Range (LoRa), Sigfox, an…
Exploring LR-FHSS Modulation for Enhanced IoT Connectivity: A Measurement Campaign
Alexis Delplace, Samer Lahoud, Kinda Khawam
This paper presents the first comprehensive real-world measurement campaign comparing LR-FHSS and LoRa modulations within LoRaWAN networks in urban environments. Conducted in Halif…
Semantic Communication with Distribution Learning through Sequential Observations
Samer Lahoud, Kinda Khawam
Semantic communication aims to convey meaning rather than bit-perfect reproduction, representing a paradigm shift from traditional communication. This paper investigates distributi…
Client Selection Strategies for Federated Semantic Communications in Heterogeneous IoT Networks
Samer Lahoud, Kinda Khawam
The exponential growth of IoT devices presents critical challenges in bandwidth-constrained wireless networks, particularly regarding efficient data transmission and privacy preser…
Fragment-Level Macro-Diversity Reception in LoRaWAN Networks with LR-FHSS
Samer Lahoud, Kinda Khawam
