METHOD AND DEVICE FOR ESTIMATION AND CORRECTION OF I/Q MISMATCH USING ITERATIVE LOOPS

摘要

The invention proposes a method for correcting and/or estimating an in- phase/quadrature-phase mismatch on a random received signal in a radio receiving device, said method causing the device to perform: -processing the random received signal in order to obtain an in-phase component and a quadrature-phase component, -amplifying and digitally converting the in-phase component in order to obtain in-phase samples, -amplifying and digitally converting the quadrature-phase component in order to obtain quadrature-phase samples, -correcting and/or estimating in-phase/quadrature-phase mismatch based on in- phase samples and quadrature-phase samples, the estimating of the in- phase/quadrature-phase mismatch being performed using two estimation loops.
