Deep Learning-based Channel Estimation for Beamspace mmWave Massive MIMO SystemsFeb 05 2018Jan 14 2019Channel estimation is very challenging when the receiver is equipped with a limited number of radio-frequency (RF) chains in beamspace millimeter-wave (mmWave) massive multiple-input and multiple-output systems. To solve this problem, we exploit a learned ... More

Beamspace Channel Estimation in mmWave Systems via Cosparse Image Reconstruction TechniqueJul 28 2017This paper considers the beamspace channel estimation problem in 3D lens antenna array under a millimeter-wave communication system. We analyze the focusing capability of the 3D lens antenna array and the sparsity of the beamspace channel response matrix. ... More

Thermal gravitational-wave background in the general pre-inflationary scenarioAug 15 2016Jan 16 2017We investigate the primordial gravitational waves (PGWs) in the general scenario where the inflation is preceded by a pre-inflationary stage with the effective equation of state $w$. Comparing with the results in the usual inflationary models, the power ... More
