Abstract:
In OFDM systems, in-phase and quadrature (I/Q) imbalances generated in the analog front-end introduce interchannel interference and, consequently, error performance degradation. This paper provides an exact expression involving the twodimensional (2-D) Gaussian Q-function for the error probability of an arbitrary 2-D modulated OFDM signal with I/Q imbalances in frequency-flat Rayleigh fading channel.
