Joint Doppler and Channel Estimation with Nested Arrays for Millimeter Wave Communications
Xiaohuan Wu, Wei-Ping Zhu, Min Lin +1
Channel estimation is essential for precoding/combining in millimeter wave (mmWave) communications. However, accurate estimation is usually difficult because the receiver can only…

A High-resolution DOA Estimation Method with a Family of Nonconvex Penalties
Xiaohuan Wu, Wei-Ping Zhu, Jun Yan
The low-rank matrix reconstruction (LRMR) approach is widely used in direction-of-arrival (DOA) estimation. As the rank norm penalty in an LRMR is NP-hard to compute, the nuclear n…

Atomic Norm Based Localization of Far-Field and Near-Field Signals with Generalized Symmetric Arrays
Xiaohuan Wu, Wei-Ping Zhu, Jun Yan
Most localization methods for mixed far-field (FF) and near-field (NF) sources are based on uniform linear array (ULA) rather than sparse linear array (SLA). In this paper, we prop…
