Vehicular MIMO Antenna Measurements in Outdoor Environments using Coherent Base Station Scanner with Real-time Demodulation

An off-line coherent base station scanner has been proposed for evaluating vehicular MIMO antennas by utilizing the reference signal present in the downlink signal from the LTE base station. However, this system does not support TDD-LTE, and post-processing takes too long. This report introduces a coherent base station scanner capable of real-time FDD and TDD demodulation; it is verified it in outdoor environments. A prototype demonstrates good results which confirm the effectiveness of the proposal.
