Distributed MIMO With Over-the-Air Phase Calibration Integrated Into the TDD Flow
Khac-Hoang Ngo, Erik G. Larsson
Reciprocity-based, joint coherent downlink beamforming from multiple access points (APs) in distributed multiple-input multiple-output (MIMO) with independent local oscillators (LO…

Breaking the TDD Flow for Over-the-Air Phase Synchronization in Distributed Antenna Systems
Khac-Hoang Ngo, Erik G. Larsson
Phase synchronization between distributed antenna arrays requires measurements that break the standard time-division duplex (TDD) operation. We present a feasibility study on imple…
