- Abstract
- During system impairment compensation of a millimeter-wave channel sounder, phase impairment between multiple antennas easily occurs due to the short wave length. This paper introduces system impairment compensation method considering phase impairment. Two kinds of back-to-back tests are conducted: the direct-connected test and the over-the-air test. To verify the proposed method, the angle of arrival estimation results are shown.
