Asynchronous Contention Resolution-Aided ALOHA in LR-FHSS Networks
In this work, we apply an asynchronous contention resolution-aided ALOHA protocol to the recently proposed long-range frequency hopping spread spectrum (LR-FHSS) scheme, […]
Fundamental Limits of Private Information Retrieval With Unknown Cache Prefetching
The fundamental limits of private information retrieval (PIR) with unknown cache prefetching at the user are investigated in this paper. To this […]
Improving Analog Zero-Forcing Null Depth with N-bit Vector Modulators in Multi-beam Phased Array Systems
Multiantenna systems can increase the spatial reuse of the wireless spectrum by nulling the interfering directions. However, the efficiency of the spatial […]
Inter-beam Interference Reduction in Hybrid mmW Beamforming Transceivers
Practical radio frequency beamforming can suffer from high sidelobe levels which cause inter-beam interference (IBI) in multibeam transceivers. IBI can be reduced […]
Performance of a Full-Duplex System in Non-Linear and Time-Varying Self-Interference Channel
The main challenge in full-duplex transceiver design is the self-interference (SI). Analog SI isolation is performed at radio frequency (RF) signal by […]
