METHOD FOR INCREASING INTERFERENCE IMMUNITY AND CARRYING CAPACITY OF AN ADAPTIVE SW RADIO COMMUNICATION SYSTEM

摘要

FIELD: radio engineering and communication.;SUBSTANCE: invention relates to radio communication and can be used in construction of adaptive systems and complexes of SW radio communication. Method is based on step-by-step adaptation of a radio channel of a slave and a master station, performing route probing, interference environment testing, finding values of optimized parameters of a radio communication system, transmitting values of selected parameters to a master station, adjusting the receiving and transmitting paths to new optimized parameters, establishing and maintaining communication, wherein a second receiving channel is additionally introduced, consisting of identical to the first receiving channel of the receiving antenna, an antenna-feeder device and a high-frequency amplifier, as well as two-channel synchronous analogue-to-digital converter, which is connected in parallel to both receiving channels, in which amplified radio signals digitization is performed.;EFFECT: technical result consists in improvement of interference immunity and capacity of adaptive communication system with OFDM-signals under conditions of influence of narrow-band station and natural interference.;3 cl, 6 dwg
