METHODS AND APPARATUS FOR ENCODING AND DECODING SIGNALS

摘要

FIELD: communication.SUBSTANCE: invention relates to communication engineering and is intended for encoding and decoding signals. Signal encoding method includes obtaining a frequency domain signal according to an input signal; allocating predetermined bits to frequency domain signal according to a predetermined allocation rule; adjusting bit allocation for frequency domain signal when a highest frequency of frequency domain signal to which bits are allocated is greater than a predetermined value; and encoding frequency domain signal according to bit allocation for frequency domain signal.EFFECT: technical result is high accuracy of encoding and decoding signals.20 cl, 9 dwg
