FIELD: radio engineering.
SUBSTANCE: noise-immune code is shaped on sending end and transferred to communication channel; on receiving end noise-immune code is first received and then decoded including error correction and erasing, whereupon block statistics of noise-immune code is calculated using results of decoding; then mentioned statistics is used to determine communication channel parameters with independent or grouping errors; in the process results of noise-immune decoding are used first to calculate integrated block statistics of reception of noise-immune code words closest with respect to probability to 0.5 corresponding to event of noise-immune code reception with quantity of errors kept within correcting ability of noise-immune code; after that communication channel parameters are evaluated by integrated block statistics of communication channel errors.
EFFECT: enhanced precision of communication channel quality control.
