Studying the Effects of Location Offset on the Evaluation of MIMO Performance Based on the Radiated Two-Stage (RTS) Method

Research output: Contribution to journalArticlepeer-review

Abstract

The intermediate results in Stage I of the RTS method can be used to help evaluate the quality of the designed MIMO antennas, which can benefit engineers with the debugging process for MIMO systems. This is achieved by exploiting the obtained intermediate results to calculate some metrics including envelope correlation coefficient (ECC) and antenna gain imbalance (AGI). The detailed process is described in the paper. The performance evaluation is desired to be accurate. However, the user equipment (UE) location offset may exist during real measurements and this can affect the evaluation of the MIMO performance. Thus, it is of interest to study to what extent the MIMO performance evaluation is influenced by the UE location offset.
