End-to-End OTFS Prototyping on Low-Cost SDRs With Energy-Retentive Message Passing Detection

Under the controlled emulated conditions, OTFS achieves lower Bit Error Rate (BER) than the OFDM baseline, while the proposed energy-retentive sparsification provides a practical complexity–accuracy tradeoff for OTFS receiver design.

Latency-guaranteed online anti-jamming routing and distributed power control for wireless heliostat fields

Wireless connectivity can substantially reduce the deployment and maintenance cost of Concentrated Solar Power (CSP) fields, but it also exposes their control infrastructure to radio-frequency jamming. A successful attack can interrupt heliostat coordination, reduce energy harvesting, and, in extreme cases, threaten fi...

On-Orbit Computing and Caching: A Distributed Regret Learning Approach

A distributed game-theoretic framework for joint task offloading and service caching in STINs, providing provable equilibrium guarantees is developed, formulated as a non-cooperative stochastic game among IoT devices that autonomously determine their computing, association, and satellite caching strategies.

Radio and Compute Resource Allocation for SWIPT and RIS-Assisted AirComp Federated Learning

Over-the-Air Computation (AirComp) Federated Learning (FL) is actively studied as a communication-efficient technique for distributed Artificial Intelligence (AI) model training. To mitigate the impact of wireless channels on the aggregated global model while addressing client energy sustainability, recent efforts have...
