Downlink Precoding with Mixed Statistical and Imperfect Instantaneous CSI for Massive MIMO Systems
Shuang Qiu, Da Chen, Daiming Qu +2
In this paper, the feasibility of a new downlink transmission mode in massive multi-input multi-output (MIMO) systems is investigated with two types of users, i.e., the users with…
