Zusammenfassung:	Aspects of a method and system for I/Q branch equalization in OFDM systems may include determining a transfer function mismatch (R) between an in-phase processing branch, and a quadrature processing branch in an OFDM receiver. The determined transfer function mismatch may be compensated for, by applying equalization (220) after a fast Fourier transform (FFT) (238b) in an in-phase processing branch or a quadrature processing branch. The OFDM system may be compliant with, for example, UMTS LTE (EUTRA), WiMAX (IEEE 802.16), DVB-H, and WLAN (IEEE 802.11).
