Semi-Blind Post-Equalizer SINR Estimation and Dual CSI Feedback for Radar-Cellular Coexistence
Raghunandan M. Rao, Vuk Marojevic, Jeffrey H. Reed
Current cellular systems use pilot-aided statistical-channel state information (S-CSI) estimation and limited feedback schemes to aid in link adaptation and scheduling decisions. H…
Probability of Pilot Interference in Pulsed Radar-Cellular Coexistence: Fundamental Insights on Demodulation and Limited CSI Feedback
Raghunandan M. Rao, Vuk Marojevic, Jeffrey H. Reed
This paper considers an underlay pulsed radar-cellular spectrum sharing scenario, where the cellular system uses pilot-aided demodulation, statistical channel state information (S-…
Analysis of Worst-Case Interference in Underlay Radar-Massive MIMO Spectrum Sharing Scenarios
Raghunandan M. Rao, Harpeet S. Dhillon, Vuk Marojevic +1
In this paper, we consider an underlay radar-massive MIMO spectrum sharing scenario in which massive MIMO base stations (BSs) are allowed to operate outside a circular exclusion zo…
Analysis of Non-Pilot Interference on Link Adaptation and Latency in Cellular Networks
Raghunandan M. Rao, Vuk Marojevic, Jeffrey H. Reed
Modern wireless systems such as the Long-Term Evolution (LTE) and 5G New Radio (5G NR) use pilot-aided SINR estimates to adapt the transmission mode and the modulation and coding s…
Measuring Hardware Impairments with Software-Defined Radios
Vuk Marojevic, Aditya V. Padaki, Raghunandan M. Rao +1
This Innovative Practice Full Paper introduces a novel tool for educating electrical engineering students about hardware impairments in wireless communications. A radio frequency (…
Rate-Maximizing OFDM Pilot Patterns for UAV Communications in Nonstationary A2G Channels
Raghunandan M. Rao, Vuk Marojevic, Jeffrey H. Reed
In this paper, we propose and evaluate rate-maximizing pilot configurations for Unmanned Aerial Vehicle (UAV) communications employing OFDM waveforms. OFDM relies on pilot symbols…
