The imperfection on orthogonal frequency converters in the transmitter and receiver causes imbalance between in-phase and quadrature received baseband signals, which is called IQ imbalance.IQ imbalance has a negative impact of inter-carrier interference~(ICI) from the image symbol on direct-conversion transceivers for orthogonal frequency division multiplexing~(OFDM).In this manuscript, we propose a derivation algorithm of bit error rate~(BER) over additive white Gaussian noise~(AWGN) channels with IQ imbalance for the receiver, transmitter, and both receiver and transmitter.We numerically show BER versus amplitude and phase imbalance, respectively.From the analytical result, it is shown that the communication quality is worse in an extensive IQ imbalance region with completely compensation in IQ imbalance. |
