摘要：

When passing through the RF analog electronics devices of the transceiver, the information signal is subject to various distortions named 'dirty RF',which degrades the communication system performance.In this paper, we first overview dirty RF effects and then propose an analytical evaluation of the performance of OFDM system where I/Q imbalance, HPA, and phase noise effects are jointly taken into account. We also give an overview of the existed algorithms which can compensate for each RF impairments. Different parameters of these impairments are applied in order to analyze how these RF impairments affect the whole system performance.
