Low-Complexity Neural Pursuit for Line Spectral Estimation
Chenchen Liu, Wenjun Jiang, Xiaojun Yuan
In this paper, we propose a high-precision yet low-complexity framework, termed Neural Pursuit for Line Spectral Estimation (NeuPLSE), for off-grid line spectral estimation from a…
Joint Activity Detection and Channel Estimation for Massive Connectivity: Where Message Passing Meets Score-Based Generative Priors
Chang Cai, Wenjun Jiang, Xiaojun Yuan +1
Massive connectivity supports the sporadic access of a vast number of devices without requiring prior permission from the base station (BS). In such scenarios, the BS must perform…
Learning-based Block-wise Planar Channel Estimation for Time-Varying MIMO OFDM
Chenchen Liu, Wenjun Jiang, Xiaojun Yuan
In this paper, we propose a learning-based block-wise planar channel estimator (LBPCE) with high accuracy and low complexity to estimate the time-varying frequency-selective channe…
Scalable Near-Field Localization Based on Partitioned Large-Scale Antenna Array
Xiaojun Yuan, Yuqing Zheng, Mingchen Zhang +2
This paper studies a passive localization system, where an extremely large-scale antenna array (ELAA) is deployed at the base station (BS) to locate a user equipment (UE) residing…
