Adaptive Channel Estimation Based on Model-Driven Deep Learning for Wideband mmWave Systems

no code implementations28 Apr 2021 Weijie Jin, Hengtao He, Chao-Kai Wen, Shi Jin, Geoffrey Ye Li

Channel estimation in wideband millimeter-wave (mmWave) systems is very challenging due to the beam squint effect.

Beamspace Channel Estimation for Wideband Millimeter-Wave MIMO: A Model-Driven Unsupervised Learning Approach

no code implementations30 Jun 2020 Hengtao He, Rui Wang, Weijie Jin, Shi Jin, Chao-Kai Wen, Geoffrey Ye Li

By utilizing the Stein's unbiased risk estimator loss, the LDGEC network can be trained only with limited measurements corresponding to the pilot symbols, instead of the real channel data.
