<p>The method involves receiving a signal (S) modulated in n-phase shift keying (PSK) or n-amplitude and PSK comprising symbols organized in frames, where each frame has a header followed by blocks of data symbols separated by blocks of pilot symbols. The header and the symbols are pre-equalized based on equalization coefficients (Hi, Hi') used to equalize the data symbols. Phase of the headers and pilot blocks is determined to predict an evolution of a signal phase. Phase corrected data symbols are equalized using the coefficients estimated based on estimated/known symbols of the signal. An independent claim is also included for a demodulator for demodulating a signal modulated in n-phase shift keying or n-amplitude and phase shift keying.</p> |
