METHOD FOR ADAPTIVE TRANSFER OF DATA IN RADIO LINK WITH PSEUDO-RANDOM TUNING OF WORKING FREQUENCY Russian patent published in 2009 - IPC H04J13/06 

FIELD: physics, radio.

SUBSTANCE: invention is related to the field of radio engineering and may find application in adaptive systems of special radio communication for data transfer along radio channel under conditions of purposive noise complex effect. Method is characterised by the fact that on transmitting end of radio link information speed is transformed into technical speed with separation of information packets comprising frames and slots, values of variables for generation of which are defined in process of radio communication, modulation of information and service slots at appropriate frequencies of transmission in compliance with the first pseudo-random sequence (PRS); on receiving end - separation of accepted signal is done into service and information parts, for service parts on appropriate frequencies in compliance with the second PRS transmission channel is selected, generation of clock signal, peaks of mutual-correlation function for accurate synchronisation during demodulation, quality of received clock sequence is analysed, and this analysis is used to define error probability per service bit, which is transferred in service frames to transmitting side, for information part demodulation of service frames is carried out at appropriate frequencies of reception in compliance with the first PRS, variable values received during demodulation are used for generation of the following packet, at that received information frame is used to analyse quality of information with separation of error per information bit, which is sent in service frames to transmitting side, and also used for calculation of probability of correct reception of possible methods of noise-immune coding.

EFFECT: introduction of clock signal processing adaptation to changes of noise environment and reduction of information losses during reception.
