ABSTRACT:
The invention concerns a method for the correction of the IQ imbalance of a receiver, in order to obtain a corrected estimate of the IQ imbalance, including:a step for estimating IQ imbalance according to imbalance residual variations since a preceding estimate of the IQ imbalance,a step correcting frequency and clock offsets,a step for correcting the IQ imbalance according to the estimate of the imbalance, in order to obtain a corrected estimate of the IQ imbalance.
