Abstract
An arrangement for processing a received wireless communication signal is disclosed. The arrangement comprises a frequency offset compensation unit adapted to apply a frequency offset compensation to the received wireless communication signal, determination circuitry adapted to determine one or more adjustment values associated with the frequency offset compensation, and an FFT-unit adapted to transform the frequency offset compensated received signal to a frequency domain. The arrangement also comprises an IQ-imbalance estimator adapted to estimate an IQ-imbalance, and an IQ-imbalance compensation unit adapted to perform IQ-imbalance compensation of the received wireless communication signal based on the estimated IQ-imbalance. At least one of the IQ-imbalance estimator and the IQ-imbalance compensation unit is adapted to base its operation on the one or more adjustment values. Corresponding method and computer program product are also disclosed.
