Downlink Performance of Superimposed Pilots in Massive MIMO systems
Karthik Upadhya, Sergiy A. Vorobyov, Mikko Vehkapera
In this paper, we investigate the downlink throughput performance of a massive multiple-input multiple-output (MIMO) system that employs superimposed pilots for channel estimation.…

Superimposed Pilots are Superior for Mitigating Pilot Contamination in Massive MIMO
Karthik Upadhya, Sergiy A. Vorobyov, Mikko Vehkapera
In this paper, superimposed pilots are introduced as an alternative to time-multiplexed pilot and data symbols for mitigating pilot contamination in massive multiple-input multiple…
