Towards Complex Over-The-Air Calibration of a MIMO mmWave Testbed
Paper i proceeding, 2023
Calibration of mm-wave transceiver arrays with respect to phase and amplitude of signals on all its antenna elements is essential for proper operation. Moreover, during operation it may be necessary to update such calibration coefficients. Here we present an algorithm based on channel symmetries to calibrate both transmitter and receiver amplitude and phase in a mm-wave testbed using Over-The-Air measurements only. The algorithm is tested using the Chalmers mm-wave testbed MATE at 29 GHz.
