Abstract: A method and device for estimating the time of arrival (ToA) of a radio signal are proposed. The radio signal comprises M subsignals carried on M subcarriers, where M is an integer ≥2. The number of propagation paths and the time of arrival associated with a first path are estimated. The technique can improve ToA estimation accuracy, especially in a multipath fading channel, and reduce the need for channel information.

Abstract: This application discloses a three-dimensional audio signal coding method. After obtaining a fourth quantity of coefficients for a current frame of a three-dimensional audio signal and frequency domain feature values of the fourth quantity of coefficients, an encoder selects a third quantity of representative coefficients from the fourth quantity of coefficients based on the frequency domain feature values of the fourth quantity of coefficients, and selects a second quantity of representative virtual speakers for the current frame from a candidate virtual speaker set based on the third quantity of representative coefficients, and then encodes the current frame based on the second quantity of representative virtual speakers for the current frame to obtain a bitstream. The encoder selects the representative virtual speakers from the candidate virtual speaker set by using a small quantity of representative coefficients to represent all coefficients.
