In this paper, a new approach to the real-time calibration ( ) of a six-port recei¨er SPR by a¨eraging the recei¨ed QPSK signals is proposed. At first, the S-parametersrQ points of the six-port are calcui lated from the a¨erage of the outputs of the six-port power detectors, and then calibration par

✦ Synopsis
In this paper, a study of the simplification of real-time ( ) calibration of six-port recei¨ers SPRs is gi¨en. 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 sol¨ed in the calculation of the calibration parameters. This calibration procedure is especially suitable for QPSK reception. Modulation errors will be cancelled if the recei¨ed signal is selected for the calibration standards. SPW simulation results of 64 QAM signal reception ¨alidate the proposed calibration procedure.

## Abstract In this paper, practical approaches to implement the suppression of adjacent channel interference for direct digital six‐port receivers using compact integrated‐circuit dispersive delay lines are described and discussed in detail. Additional interference at the receiver output due to ph
In this paper, the nonlinear cross-modulation noiser interference arising from channel filtering and leakage in a six-port digital ( ) millimetric recei¨er DMR is studied in detail. The in-band noiser interference arises from strong noiserinterference outside the recei¨ing ( ) bandwidth, and will de
