Abstract: This application discloses an analog-to-digital (ADC) converter and a signal processing apparatus. In this solution, a low-power circuit in the ADC may control, based on a received indication signal, whether a first-stage sub-ADC in the ADC is to normally perform analog-to-digital conversion, so that a processing bit width of the ADC can be adjusted. When the processing bit width of the ADC is reduced, power consumption of the ADC is reduced accordingly. Therefore, this application provides a solution for reducing the power consumption of the ADC by adjusting the processing bit width of the ADC.

Abstract: A positioning method, a device, a system, a chip, and a storage medium are provided. A network device is externally connected to N antennas, the network device has N receive channels, and the N antennas are in a one-to-one correspondence with the N receive channels. The method includes: A network device receives, by using each of the N antennas, a positioning signal sent by a terminal device, determines TOA information and/or RSSI information of the positioning signal on each of the N receive channels, and sends the TOA information and/or the RSSI information of the positioning signal on each of the N receive channels to a service anchor. The service anchor is configured to position the terminal device based on the TOA information and/or the RSSI information.

Abstract: The present disclosure provides a communication method and apparatus. In an example, the communication method may include: transmitting a first radar transmit signal in a first frequency band by using a first transmit antenna array; receiving a first echo signal of the first radar transmit signal in the first frequency band by using a first receive antenna array, where the first echo signal includes an echo signal corresponding to at least one first terminal; and communicating with at least one second terminal in a second frequency band by using a second transmit antenna array and a second receive antenna array, where the first frequency band and the second frequency band do not overlap.
