Interleaved Training and Training-Based Transmission Design for Hybrid Massive Antenna Downlink

, 2018
In this paper, we study the beam-based training design jointly with the transmission design for hybrid massive antenna single-user (SU) and multiple-user (MU) systems where outage probability is adopted as the performance measure.
