FIELD: radio engineering.SUBSTANCE: invention relates to radio engineering, particularly to devices designed for matched information receiving in tropospheric communication lines, and can be used to create over-the-horizon communication systems. Device comprises receiving antenna, band-pass filters, connected in parallel, switches, mixers, filters, adders, clock generator, shift register, delay lines, heterodynes, synchroniser and common adder. Using the matched information receiving devices in tropospheric communication lines can significantly reduce the loss of information channels to 50 % and, consequently increase the noise immunity and speed of information transmission, which in practice allows using transmitters with lower input power, antennas with a smaller aperture, to reduce the number of receiving antennas, as well as to increase the distance between transmitter and receiver, which generally increases the economic benefit from the use of mentioned device.EFFECT: technical result consists in reducing the fading effect when receiving information in tropospheric communication lines, higher information transmission speed and noise-immunity of communication with a minimum amount of signal generating and processing channels.2 cl, 2 dwg |
