| Abstract(in English) | As the frequency bandwidth in wireless communications are wide, impairments of analog circuits of transceivers including IQ imbalance become exacerbated and have frequency-dependent. In this paper, we report a blind compensation technique for frequency-dependent IQ imbalance of OFDM systems using constant norm algorithm (CNA). It shows better transmission performance compared to conventional constant modulus algorithm (CMA). |
