Performance comparisons of FDD MIMO and 2.6 GHz TDD massive MIMO: An experimental analysis

Massive multiple-input multiple-output (MIMO) is considered as a breakthrough technology in 5G and beyond 5G systems. Some of its main advantages are providing high spectral efficiency to many users simultaneously in the same time-frequency blocks, strong directive signals towards short-range areas...
