FIELD: radio equipment.
SUBSTANCE: invention relates to the field of radio equipment. AFC channel estimation is carried out by means of estimation of time position and complex amplitudes of beams and is performed by means of superresolution method (MUSIC), at that initial estimation is performed by sequence of pilot symbols by means of method of least squares (LS-estimation), constructing correlation evaluation matrix, calculating eigenvectors and eigenvalues of said matrix and calculating estimates of time positions of beams, performing complex amplitude amplification of beams, channel estimate for all points is constructed, modulated data symbols are corrected.
EFFECT: invention can be used in radio communication systems of multiple access with orthogonal frequency-multiplexed signals (OFDM) and is intended to increase accuracy of estimation of AFC channel.
