FIELD: physics, communication.
SUBSTANCE: invention is related to data transmission, namely, to temporal filtering for reduction of excessive delay in systems with orthogonal frequency division multiplexing with orthogonal frequency division multiplexing (OFDM, FDM). To reduce harmful effects of excessive delay duration, temporal filtering has been used in channel assessment. Temporal filtering is carried out, when pilot-signals shifted relative to each other are available.
EFFECT: reduction of harmful effects of excessive duration of delay.
