PROCESS OF RADIO SUPPRESSION OF COMMUNICATION CHANNELS Russian patent published in 2000 - IPC

FIELD: radio engineering. SUBSTANCE: proposed process can be used in equipment creating artificial interference, for selective suppression of users of present-day radio networks with macro- and microstructures, for simulation of noise signal while adjusting networks mentioned above and evaluating their capacity. Technical objective of invention consists in development of process of selective suppression of user with specified number that ensures formation of effective radio interference achieved thanks to employment of information transmitted by network proper in common signalization and call channels. Process involves multiple reception of messages transmitted in mentioned channels, bit-by-bit recording of service frames, extraction of their information part and reading from it of user's number and value of number of channel allocated for present communication session and formation of interference on two frequencies simultaneously. Owing to usage of information on communication channel one can avoid loss of time on search for required communication channel, tune noise transmitters to frequencies allocated for communication and suppress transmission of information in duplex communication channel of user with specified number. EFFECT: effective suppression of individual users of present-day communication systems with macro-and microstructures without interference into operation of other users of network. 1 cl, 6 dwg
