FIELD: information technology.
SUBSTANCE: transmitter has a frame generating unit having OFDM symbols and a unit for transmitting the generated frame, wherein the generation unit deploys the main synchronisation channel for detecting the symbol synchronisation signal in the last OFDM symbol in the frame and an auxiliary synchronisation channel for frame detection during reception in an OFDM symbol preceding the last OFDM symbol.
EFFECT: high accuracy of detecting synchronisation channels.
