FIELD: radio engineering, possible use in wireless communication systems.
SUBSTANCE: in the method, frames are found for which data transfer speeds have been determined incorrectly, and processing is performed, providing for erasing of frames and/or clearing of memory to prevent expansion of distortion among multiple frames. Frames with erratically determined speeds of data transfer are found by checking unsanctioned transitions from one speed to another and reserve bits, confirming correctness of unused combinations of bits for filter and analyzing connections between transfer coefficients of fixed encoding table and transfer coefficients for linear prediction.
EFFECT: decreased appearance of sound artifacts, such as creaks or background signals, caused by errors in speed determining algorithm.
