Abstract
An equalization algorithm is proposed for digital video broadcasting - terrestrial version 2 (DVB-T2) systems to minimize the noise effect. It is done by averaging frequency-domain data and channel responses obtained with different signal intervals for the same orthogonal frequency division multiplexing (OFDM) symbol. Its performance is evaluated by computer simulations along with comparison of conventional algorithms.
