FIELD: information technologies.
SUBSTANCE: receiver to receive an orthogonal frequency division multiplex (OFDM) signal of digital video broadcasting (DVB), including sets of OFDM-symbols, containing data symbols and pilot symbols, comprises an input module, arranged with the possibility to receive the OFDM DVB-signal along a transmission channel and a channel assessment module connected to the input module and arranged with the possibility to calculate estimates of the transmission channel by means of Fourier transformation of OFDM-symbols sets to produce multiple transformed sets of frequency area, and by detection of at least one set of minimum mean-square error (MMSE) filtration coefficients for at least one of transformed symbol sets, using subset of pilot symbols in one transformed symbols set.
EFFECT: improved accuracy of channel assessment.
