Abstract
An electrical system includes a transceiver with an IQ estimator and an IQ mismatch corrector. The electrical system also includes an antenna coupled to the transceiver. The IQ estimator is configured to perform frequency-domain IQ mismatch analysis to determine an IQ mismatch estimate at available frequency bins of a baseband data signal. The IQ mismatch corrector is configured to correct the baseband data signal based on the IQ mismatch estimate.
