In an orthogonal frequency division multiplexing (OFDM) system, in-phase and quadrature (I/Q) imbalances generated in the analog front-end introduce inter-channel interference (ICI) and, consequently, error performance degradation. In this paper, a general and exact expression involving the two-dimensional (2-D) Gaussian Q-function for symbol error probability of MPSK-OFDM signal with I/Q imbalances is provided. The effect of I/Q imbalances on the error performance and the distribution of an additive white Gaussian noise (AWGN) on the signal constellation are also exactly analyzed.
