In this paper, a study of the simplification of real‐time calibration of six‐port receivers (SPRs) is given. A simple, real‐time calibration procedure is proposed using the incoming QPSK signal as the calibration standard. Only two systems of four linear equations are necessary to be solved in the calculation of the calibration parameters. This calibration procedure is especially suitable for QPSK reception. Modulation errors will be cancelled if the received signal is selected for the calibration standards. SPW simulation results of 64 QAM signal reception validate the proposed calibration procedure. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 20: 318–322, 1999.
