METHOD FOR FREQUENCY SOUNDING, COMBINED WITH DATA TRANSFER PROCESS Russian patent published in 2019 - IPC H03L1/04 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication technology and can be used in duplex and half duplex asynchronous data transmission systems with a feedback channel. In the method, the process of transmitting information at the selected frequency is interleaved with the transmission of individual information blocks at other allocated frequencies, at the same time, at the search frequencies, information blocks of a given length are transmitted, but not test blocks previously known on the receiving side, which do not carry information load. At the same time, for each information block, within its length, an assessment of signal-interference conditions or the quality of the corresponding frequency is carried out. Sounding for dialing and maintaining an elite group of frequencies occurs in the process of transmitting data without reducing the information speed.

EFFECT: technical result consists in increasing the reliability of the data transmission system by monitoring the state of the allocated frequency resource that does not reduce the information data transfer rate.
