ST-DDA: Dynamic Channel Estimation in the Doppler-Delay-Angle Domain via Sparse Subspace Tracking for TDD Systems

Xu Zhu, Tiejun Li

Accurate full-band channel acquisition in frequency-hopping time-division duplex (TDD) systems is challenging because each sounding slot observes only a limited frequency subband,…

Dual-Mapping Sparse Vector Coding for Phase Noise-Resilient Short-Packet Transmission

Yanfeng Zhang, Xi'an Fan, Xu Zhu +6

Sparse vector transmission (SVT) has emerged as a promising technique for ultra-reliable low-latency short-packet communications. However, existing SVT schemes typically assume neg…

Covering-radius and Collinearity- Minimizing Pilots for Channel Estimation in TDD Systems

Xu Zhu, Yi Zeng, Tiejun Li

This letter studies pilot design for orthogonal frequency-division multiplexing-based time-division duplex (TDD) systems under a sliding-window latest-slot recovery framework that…

DDA-Net: Accurate TDD Channel Estimation via Deep Unfolding the Doppler-Delay-Angle Representation of Channel Signals

Yufei Ma, Xu Zhu, Tiejun Li

In TDD massive MIMO systems, channel estimation under sparse frequency-hopping pilots is challenging: each snapshot captures only one narrow pilot block that hops across frequency,…
