Calibration techniques for fully parallel 24 × 24 MIMO sounder

In this paper, the calibration techniques for the fully parallel MIMO sounder was introduced. A simplified B2B calibration measurement method was also proposed. With the automatic calibration processes and the simplified B2B measurement method, it is possible to shorten the time greatly for the calibrations, which provides a solution to the major drawback in a fully parallel architecture of the developed MIMO channel sounder.
