"EVRYKA - V V V" DATA TRANSMISSION SYSTEM THROUGH THE ANALOG PADIO RELAY FEEDS

A data transmission system through analog radio relay feed consists of a line links unit as part of transmission and receive line channel that is connected to an antenna system as part of transmitting and receiving antenna, a frequency modulator and a frequency demodulator, a DVB-C digital flow former having output connected to DVB-C modulator input and DVB-C demodulator. Frequency modulator output is connected to transmission line channel input of line links unit. Frequency demodulator input is connected to output of receiving line channel of line links unit. Additionally it is introduced a digital flow former of data in PDF format having input for connection of an information source and output connected to input of a PDF digital flow modem that additionally contains facilities for direct and back converting of PDH and DVB formats, modulation and demodulation of DVB-C flows, modulatior and demodulatior of DVB-C standards. RF power modem output is connected to input of a radio signals combiner, output of DVB-C modulator is connected to another input of the combiner. Output of the radio signals combiner - to frequency modulator input. Also, the system includes a frequency radio signal distributor having input connected to frequency demodulator output, one output is connected to modem of PDH standard, another - to demodulator of DVB-C.
