no code implementations25 Apr 2024 Bo Peng, Xiaofeng Li, Xinyu Li, Zhenghan Wang, Hui Deng, Xiaoxian Luo, Lixue Yin, Hongmei Zhang

Hypertrophic cardiomyopathy (HCM) and cardiac amyloidosis (CA) are both heart conditions that can progress to heart failure if untreated.

Deep Learning for Joint Design of Pilot, Channel Feedback, and Hybrid Beamforming in FDD Massive MIMO-OFDM Systems

no code implementations10 Dec 2023 Junyi Yang, Weifeng Zhu, Shu Sun, Xiaofeng Li, Xingqin Lin, Meixia Tao

This letter considers the transceiver design in frequency division duplex (FDD) massive multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems for high-quality data transmission.

SNR-based beaconless multi-scan link acquisition model with vibration for LEO-to-ground laser communication

no code implementations6 Aug 2023 Sen yang, Xiaofeng Li

Specially, under the combined effects of platform vibration and turbulence, we decouple the parameters of beam divergence angle, spiral pitch, and coverage factor at a fixed transmitted power for a given average received SNR threshold.

Deep Learning for Direct Hybrid Precoding in Millimeter Wave Massive MIMO Systems

2 code implementations30 May 2019 Xiaofeng Li, Ahmed Alkhateeb

For example, for a system of 64 transmit and 64 receive antennas, with 3 RF chains at both sides, the proposed solution needs only 8 or 16 channel training pilots to directly predict the RF beamforming/combining vectors of the hybrid architectures and achieve near-optimal achievable rates.

Optimal Training for Residual Self-Interference for Full-Duplex One-Way Relays

no code implementations13 Aug 2018 Xiaofeng Li, Cihan Tepedelenlio˘glu, and Habib ¸Senol, Member, IEEE

For the former, we propose a training scheme to estimate the overall channel, and for the latter the CRB and the optimal number of relays are derived when the distance between the source and the destination is fixed.

Generative Adversarial Estimation of Channel Covariance in Vehicular Millimeter Wave Systems

no code implementations7 Aug 2018 Xiaofeng Li, Ahmed Alkhateeb, Cihan Tepedelenlioğlu

Enabling highly-mobile millimeter wave (mmWave) systems is challenging because of the huge training overhead associated with acquiring the channel knowledge or designing the narrow beams.
