DEVICE FOR SYNCHRONISATION IN RADIO COMMUNICATION SYSTEM WITH PROGRAMMED OPERATIONAL FREQUENCY TUNING

摘要

FIELD: physics, radio.SUBSTANCE: invention relates to radio engineering and can be used in radio communication systems with programmed (pseudorandom) operational frequency tuning. To this end, one device combines the functions of determining signal time delay and signal frequency shift, and time spent on synchronising and determining Doppler frequency shift is reduced. Information signals with pseudorandom operational frequency tuning that are identical on form are used during synchronisation. The device is further simplified by excluding parallel receiving channels.EFFECT: providing operation of a radio communication system in Doppler effect conditions, high noise-immunity and reconnaissance-security of a radio link.1 dwg
