Beam-On-Graph: Simultaneous Channel Estimation for mmWave MIMO Systems With Multiple Users

This paper is concerned with the channel estimation problem in multi-user millimeter wave wireless systems with large antenna arrays. We develop a novel simultaneous-estimation with iterative fountain training (SWIFT) framework, in which multiple users estimate their channels at the same time and the required number of channel measurements is adapted to various channel conditions of different users. To achieve this, we represent the beam...
