DEVICE FOR ESTIMATION AND CORRECTION OF PARAMETRES OF CHANNEL FOR RECEPTION OF COFDM-SIGNALS

摘要

FIELD: information technologies. ^ SUBSTANCE: invention may be used in devices that operate in DVB-T standard and other broadband systems using COFDM-modulation. Algorithm is used, which makes it possible to increase speed of correcting coefficients convergence, and to eliminate operations of division and Fourier inversion in process of their calculation. ^ EFFECT: improved efficiency and accuracy of recovery of frequency characteristic of channel under conditions of symbol-to-symbol interference. ^ 12 dwg
