Millimeter Wave Channel Estimation via Exploiting Joint Sparse and Low-Rank Structures
Xingjian Li, Jun Fang, Hongbin Li +1
We consider the problem of channel estimation for millimeter wave (mmWave) systems, where, to minimize the hardware complexity and power consumption, an analog transmit beamforming…
Channel Estimation for Millimeter Wave Multiuser MIMO Systems via PARAFAC Decomposition
Zhou Zhou, Jun Fang, Linxiao Yang +3
We consider the problem of uplink channel estimation for millimeter wave (mmWave) systems, where the base station (BS) and mobile stations (MSs) are equipped with large antenna arr…
Sparse Bayesian Dictionary Learning with a Gaussian Hierarchical Model
Linxiao Yang, Jun Fang, Hong Cheng +1
We consider a dictionary learning problem whose objective is to design a dictionary such that the signals admits a sparse or an approximate sparse representation over the learned d…
A Fast Iterative Algorithm for Recovery of Sparse Signals from One-Bit Quantized Measurements
Jun Fang, Yanning Shen, Hongbin Li
This paper considers the problem of reconstructing sparse or compressible signals from one-bit quantized measurements. We study a new method that uses a log-sum penalty function, a…
A New Determinant Inequality of Positive Semi-Definite Matrices
Jun Fang, Hongbin Li
A new determinant inequality of positive semidefinite matrices is discovered and proved by us. This new inequality is useful for attacking and solving a variety of optimization pro…
