Abstract
Methods, systems, and apparatuses are described for compensating for impairments of a wireless device. In accordance with a disclosed method, a set of equalizer taps for an analog pipeline of the wireless device is determined. A first set of complex filter taps and a second set of complex filter taps are also determined, by modifying the set of equalizer taps according to an estimated imbalance of the analog pipeline of the wireless device. A signal associated with the analog pipeline is processed with a complex filter according to the first set of complex filter taps and the second set of complex filter taps. The processing provides a combined imbalance compensation and equalization of the signal. The complex filter may include a first complex half-filter associated with the first set of complex filter taps and a second complex half-filter associated with the second set of complex filter taps.
