Original Abstract Submitted

This application provides a signal transmission method, apparatus, and system. The method includes: generating an ultra-wideband signal, where the ultra-wideband signal includes a channel impulse response training sequence (CTS) field, and the CTS field is obtained by separately spreading at least one first preamble symbol based on a pseudo-random sequence; and sending the ultra-wideband signal, where the CTS field is used to determine a channel impulse response. This application can effectively improve ranging and positioning efficiency while implementing secure high-precision ranging and positioning.
