Frequency-domain delay distortion equalization-the complex spectrum regeneration method

In radio communications, equalization of delay distortion due to multipath propagation is one of the most necessary and difficult problems. There are two equalization methods, i.e., the time-domain method and frequency-domain method. The frequency-domain linear equalization, in which equalization is performed by deconvolution of the received signal by the transfer function of the propagation path is presented. Since this method is implemented by software-based devices, faster, stable, and more adaptive equalization is possible
