Kind Code:
A1
Abstract:
The present application provides a signal transmission method, device and system. The method comprises: generating an ultra-wideband signal, the ultra-wideband signal comprising a channel impulse response training sequence (CTS) field, and the CTS field being obtained by respectively performing spectrum spreading on at least one first preamble symbol by means of a pseudorandom sequence; and sending the ultra-wideband signal, wherein the CTS field is used for determining a channel impulse response. According to the present application, the ranging and positioning efficiency can be effectively improved while secure high-precision ranging and positioning are realized.
