Robust Angle Estimation for Hybrid mmWave Systems

ICASSP 2023accepted

In this paper, we consider robust channel estimation for a millimeter wave (mmWave) massive MIMO system that is equipped with uniform linear arrays (ULA). Most current angle estimation methods for mmWave systems are developed for time-varying or time-invariant channels. We propose a robust method th…

Feedback of differential precoder for geometrical mean decomposition systems

Hung-Chun Chen, Yuan-Pei Lin

ICASSP 2016accepted

For a time-correlated channel, we consider the differential feedback of the geometrical mean decomposition (GMD) precoder, which is known to be optimal for a number of criteria. When the channel varies slowly, we can expect the optimal GMD precoders of consecutive channel uses to be close. We consid…
