Abstract

The present invention concerns a method and device for demodulating received symbols using a turbo equalization loop for a single carrier system. A receiver:- performs a discrete Fourier transform on the received symbols,- equalizes the discrete Fourier transform received symbols in order to obtain equalized symbols,- executes an inverse discrete Fourier transform on the equalized symbols in order to obtain equalized symbols in the time domain,- executes a first subtracting step by subtracting, from equalized symbols in the time domain, non-linear interference,- de-maps the output of the first subtracting,- decodes the output of the de-mapping,- executes a second subtracting by subtracting, from the output of decoding, the input of the decoding,and the output of second subtracting is provided to the equalization, to the non-linear interference generation, the non-linear interference being obtained by a Volterra series, the coefficients of which are determined from the equalized symbols in the time domain.
