Abstract: FIELD: communication equipment. 
     SUBSTANCE: invention relates to communication engineering and can be used for soft decoding of a noise-immune code in high-noise communication channels. At the input of the decoding device, n symbols of the received noise-immune code are sent with estimates of reliability of symbols. In the decoding device of the noise-immune code, the value s of the number of least reliable symbols of the noise-immune code is first evaluated, then the symbols of the noise-immune code are sorted by reliability and selecting s least reliable symbols and n-s most reliable code symbols. Using the code check matrix, the least reliable symbols are calculated through the most reliable code symbols. Decoding is completed if all verification code ratios are satisfied, otherwise verification is selected in verification matrix, which includes more valid symbols compared to symbols of other checks and calculating the least reliable symbol and its new validity. All checks of the verification matrix are substituted with the newly calculated symbol taking into account the new validity and s-1 least reliable symbols are calculated again. 
     EFFECT: technical result consists in improvement of decoding efficiency while maintaining high noise immunity.

Abstract: FIELD: radar technology.  
     SUBSTANCE: invention relates to the field of radar and can be used in radar stations (radio detectors) to improve the quality of detection of modulated signals against the background of passive interference (PI). The claimed method consists in storing signs of detecting the presence/absence of a signal after additional interperiod processing (AIPP) and basic interperiod processing (BIPP) coming from an input data processing device. The number of spatial clusters is set for which the sum of signs of detecting a signal that has exceeded the noise threshold (SENT) is calculated and stored; the number of the review cycle on which the sum of signs of detecting the SENT has been changed; signal amplitudes after interperiod processing, for the current review cycle; maximum amplitudes after interperiod processing, for the current review cycle; signs of detecting point objects with a Doppler frequency shift after interperiod processing, signal rejection coefficients after AIPP relative to BIPP with corresponding AIPP numbers. Further, the maximum amplitudes in the clusters are used to isolate PI from external and intrinsic noise by comparing with threshold values and forming signs of excess. After the formation of signs of excess over the threshold values and signs of detection of point objects with a Doppler frequency shift, the signs of the SENT are accumulated and the numbers of the survey cycles in clusters are changed, the values of the accumulated signs of the SENT are checked, the values lie in the specified intervals; the information in clusters that have not been modified is checked, the cycle number is changed for the current one, and the sum of the signs of the SENT is reduced by one. The accumulated values of the sum of the features of the SENT are compared with the criterion for detecting PI, obtaining the detection of PI in clusters. The gates of detected PI are expanded, as a result of which PI gates are formed, as well as signs of their expansion and signs of detected point objects with a Doppler frequency shift. The numbers of interperiod processing (IPP) for clusters are selected according to the coefficients of signal rejection after AIPP relative to BIPP, according to which protection against PI is assigned and signs of the presence/absence of detected signals are selected.   
     EFFECT: providing automatic assignment of protection against PI for pulse-Doppler radars.
