Abstract

At least one example embodiments discloses a method of compensating for in-phase and quadrature (IQ) imbalance in a base station. The method includes generating, at the base station, compensation filter weights based on a plurality of IQ imbalanced training signals, the generating including, determining the compensation filter weights based on the plurality of imbalanced training signals in a frequency domain. The method further includes filtering based on the compensation filter weights.
