Near-Optimal Pilot Signal Design for FDD Massive MIMO System: An Energy-Efficient Perspective
This paper investigates the pilot signal design for a massive multiple-input multiple-out (MIMO) frequency division duplexing downlink system by taking the channel spatial correlation into account. Our objective is to optimize the pilot pattern, including the pilot power and structure, from the pers...
