FIELD: information technology.
SUBSTANCE: invention relates to systems and methods of determining a set of interpolation coefficients. Method for determining a set of interpolation coefficients by means of electronic device includes determination of a value based on property of current frame and property of previous frame, determination of whether or not value is outside a range, determination of set of interpolation coefficients based on value and prediction mode indicator, if value is outside range.
EFFECT: technical result consists in optimisation of throughput, thereby balancing desired average bit rate of recovered voice signal.
