Abstract
Comparing with Radio frequency calibration technology, the main channel calibration part of Digital calibration technology is done in the digital part, which is mainly achieved by means of digital filters, digital delay lines, etc. In 5G MIMO antenna system, two channels share one crystal oscillator, real-time calibration needs to be done when rebooting the system. Based on this problem, a new digital calibration algorithm of integrative transceiver including the initial phase of the crystal oscillator is proposed in this paper. Related tests of antennas and arrays are also carried out.
