SINOPSIS

The parameters of the DVB-C standard multichannel digital TV signal are studied at transmission via the 130 GHz band transceiver model. The investigation results showed that use of the lower part of the terahertz frequency band (130 GHz) with the 24 MHz bandwidth allows transmitting three channels of the DVB-C standard television broadcasting with the total traffic transmission rate at the level of 125 Mbps with the high subjective quality of TV program reproduction. The results of modeling of the transmission using the pulse broadband signal (IR-UWB) heterodyning method by the terahertz band radio link are provided. The results of the investigations (temporal form variations) are determined for the first time at transmission of the IR-UWB signal in the form of the Gaussian monocycle via the transmitting path and its reception with the terahertz receiving path in the frequency bandwidth of 130.4...131.5 GHz. On the basis of the obtained investigation results the requirements to the terahertz band radio link parameters are formulated in order to provide for the acceptable quality of reception of the pulse ultrawideband signals. Development of the transceiver of the terahertz band radio relay system has no direct analogs presently that can provide for a substantial breakthrough in development of the telecommunications sector. The obtained investigation results would also facilitate development of the sectors adjacent to the telecommunications, in particular – radio astronomy, satellite-to-satellite communication, radars, medical science etc.
