Map2APS: A Physically Grounded Benchmark for Direct Angle Power Spectrum Prediction from Urban Geometry
Junxi Huang, Xiucheng Wang, Nan Cheng +3
Angle power spectrum (APS) characterizes the directional distribution of received signal power and is directly relevant to beam management and MIMO processing. While environment-aw…
Beyond the Delay-Doppler Domain: A Time-Frequency Framework for Low-Overhead, Scalable OTFS Channel Estimation
Kailong Wang, Athina Petropulu
Most works on pilot-aided orthogonal time frequency space (OTFS) channel estimation operate in the delay-Doppler (DD) domain, where embedded-pilot guard regions must cover the unkn…
ISAC MIMO Systems with OTFS Waveforms and Virtual Arrays
Kailong Wang, Athina Petropulu
A novel Integrated Sensing-Communication (ISAC) system is proposed that can accommodate high mobility scenarios while making efficient use of bandwidth for both communication and s…
Virtual Array for Dual Function MIMO Radar Communication Systems using OTFS Waveforms
Kailong Wang, Athina Petropulu
A MIMO dual-function radar communication (DFRC) system transmitting orthogonal time frequency space (OTFS) waveforms is considered. A key advantage of MIMO radar is its ability to…
