Resumen:
In this paper, two non-desired effects,interference and in-phase/quadrature (I/Q) imbalance,are jointly compensated at the receiver sideof an Orthogonal Frequency Division Multiplexing(OFDM) system. Taking information of the knownpilots transmitted within the symbol, a Post-FFT receiverbeamforming based on an NLMS algorithm isproposed to adapt the beamforming weights to rejectinterference signals and to compensate I/Q imbalance.Our simulation results show that the proposed Post-FFT receiver beamforming compensates I/Q imbalancewithout degrading the interference rejection ofthe array.
