Abstract
The invention relates to the field of the equalizer, more specifically, to a single carrier equalizer and a receiver system comprises the single carrier equalizer. It is used to gradually improve the performance of the frequency domain equalizer by the way of iterations. The present invention uses an iterative updater to conduct a first iteration based on the frequency domain value of the input signal and the frequency domain value of the channel of the input signal, and transmits the iteration result to the inverse fast Fourier transformer. And the signal decision device is used to judge the value of the output of the inverse fast Fourier transformer, and the output signal of the signal decision device is transmitted to the fast Fourier transformer and the iterative updater respectively.
