摘要：

One of the serious imperfections affecting OFDM systems is transceiver I/Q imbalance. In this letter, closed-form expressions for the outage probability of beamforming OFDM systems with transmit and receive I/Q imbalances are derived. Moreover, the asymptotic behavior and diversity order of the system is investigated. The analytical results are confirmed by simulations.
