摘要：

We propose a new algorithm for the IQ imbalance estimation and equalization of an Orthogonal Frequency Division Multiplexing (OFDM) system in the presence of a Carrier Frequency Offset (CFO) and of a dense multipath environment. Our algorithm has a low complexity and needs a single pilot symbol. Through numerical simulation and in the context of quick estimations of front-end non-idealities, our algorithm is shown to outperform conventional approaches for sensible values of IQ imbalance and CFO.
