FIELD: radio engineering.
SUBSTANCE: invention relates to radio communication hardware and can be used in wireless systems designed to use data array for facilitating selected signal detection. Data can be retrieved from previous data via estimation of changes observed in such parametres, as time and location, which endanger validity. In some cases, data can be corrected to suits parametre variations. Corrected data can be calculated by receiver with the help of incomplete measurements of signal sets, particularly if data intended for facilitating signal detection from remote source incorporate parameters notably different from those usually supplied. New data shall not be obligatorily received until validity of previous data expires due to constraints to time interpolation via Doppler coefficients, is mobile station displacement is not identified.
EFFECT: reduced data processing and exchange load in receivers.
