Sparse Channel Estimation for Pixel Antennas: Addressing the Pilot Rank Deficiency
Yiting Chen, Yumeng Zhang, Hongyu Li
Composed of multiple interconnected pixels controlled by on/off RF switches, the pixel antenna can generate reconfigurable radiation patterns that can be further exploited to const…
GeoGS-CE: Learning Delay--Beam Channel Priors with 3D Gaussians for High-Mobility Scenarios
Yumeng Zhang, Jiajia Guo, Chaozheng Wen +2
Wideband channel estimation (CE) in high-mobility scenarios remains challenging because channel responses vary rapidly, while practical systems can allocate only sparse pilots to a…
LISAC: Learned Coded Waveform Design for ISAC with OFDM
Chenghong Bian, Yumeng Zhang, Meng Hua +2
We propose deep learning based coded waveform design for integrated sensing and communication (ISAC) with orthogonal frequency-division multiplexing (OFDM). Our goal is to design a…
CRC-Assisted Channel Codes for Integrated Passive Sensing and Communications
Chenghong Bian, Kaitao Meng, Huihui Wu +2
We propose a novel coded integrated passive sensing and communication (CIPSAC) system with orthogonal frequency division multiplexing (OFDM), where a multi-antenna base station (BS…
