<p>Estimation of phase and gain mismatch between the real part and the imaginary part of a baseband digital signal. It comprises: estimating phase and gain mismatch values for each of a plurality of subbands of said baseband digital signal; determining weight coefficients depending upon the likelihood of the frequency values for each subband; and determining the phase and gain mismatch for the baseband digital signal using said weight coefficients.</p> |
