Spectrally efficient FDM (SEFDM) was proposed as a spectrally efficient scheme. An iterative fast Fourier transform (FFT) detector jointly operating with a channel decoder was also proposed for coded SEFDM. Unfortunately, the iterative FFT detector requires relatively high complexity for some bandwidth compression factors. A new detection scheme for the coded SEFDM is proposed. In the proposed scheme, the inter‐carrier interference is iteratively estimated and cancelled in frequency domain. The proposed scheme not only offers virtually identical performance but also requires less complexity compared with the iterative FFT detector.
