FREQUENCY-ADAPTIVE RADIO LINE FOR TRANSMISSION OF MEDIUM-SPEED DIGITAL INFORMATION STREAMS Russian patent published in 1999 - IPC

FIELD: radio communication equipment. SUBSTANCE: device uses independent frequency adaptation to each sub-channel of multiple-frequency group signal. This results in possibility to eliminate communication delays for switching frequencies of sub- channels which are adversely effected by noise in order to decrease density of stream of alternations of fixed transmission frequencies. Device has receiver, transmitter, radiometric unit, units of modulators and demodulators, units for encoding and decoding commands, units for setting reception and transmission reference frequencies, unit for generation of key code. Goal of invention is achieved by introduced units for commutation of reception and transmission reference frequencies, increased range of functions to be achieved by unit for selection of optimal sub-channels, information regeneration and combination unit, and assembly of solving devices. EFFECT: development of medium-speed frequency-adaptive radio line with multiple-frequency transmission mode which transmission capacity is not sensitive to noise at fixed communication frequency. 8 cl, 8 dwg
