Abstract
This application provides a signal transmission method and apparatus, applied to automatic driving, assisted driving, and the like. The method includes: A first device generates a first signal, where the first signal includes a first part and a second part, the second part is modulated in a phase shift keying PSK modulation scheme, the second part is encoded by using polar code, the first part is used to transmit a preconfigured sequence, a predefined sequence, or a sequence generated according to a predefined rule, and the second part is used to transmit control information. The first device sends the first signal to a second device. The second device obtains the control information. The PSK modulation scheme can improve sensitivity of a signal receive end, and improve anti-noise and anti-interference capabilities. In addition, the second part is encoded by using the polar code, which can improve anti-noise and anti-interference performance.
