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…
Downlink Power Control based UE-Sided Initial Access for Tactical 5G NR
Akshay Jain, Karthik Upadhya, Mikko A. Uusitalo +1
Communication technologies play a crucial role in battlefields. They are an inalienable part of any tactical response, whether at the battlefront or inland. Such scenarios require…
LPD-Aware Uplink CSI-based 5G NR Downlink Synchronization for Tactical Networks
Karthik Upadhya, Akshay Jain, Mikko A. Uusitalo +1
5G NR is touted to be an attractive candidate for tactical networks owing to its versatility, scalability, and low cost. However, tactical networks need to be stealthy, where an ad…
A generalization of the achievable rate of a MISO system using Bode-Fano wideband matching theory
Nitish Deshpande, Miguel R. Castellanos, Saeed R. Khosravirad +3
Impedance-matching networks affect power transfer from the radio frequency (RF) chains to the antennas. Their design impacts the signal to noise ratio (SNR) and the achievable rate…
A wideband generalization of the near-field region for extremely large phased-arrays
Nitish Deshpande, Miguel R. Castellanos, Saeed R. Khosravirad +3
The narrowband and far-field assumption in conventional wireless system design leads to a mismatch with the optimal beamforming required for wideband and near-field systems. This d…
