In this paper, we consider low-PMEPR (Peak-to-Mean Envelope
Power Ratio) MC-CDMA (Multicarrier Coded Division
Multiple Access) schemes. We develop frequencydomain
turbo equalizers combined with an iterative estimation
and cancellation of nonlinear distortion effects. Our
receivers have relatively low complexity, since they allow
FFT-based (Fast Fourier Transform) implementations. The
proposed turbo receivers allow significant performance improvements
at low and moderate SNR (Signal-to-Noise Ratio),
even when a low-PMEPR MC-CDMA transmission is
intended
