Abstract: This application provides a communication apparatus. The communication apparatus includes at least one transmit antenna unit, at least one receive antenna unit, and a signal processing unit. The signal processing unit is configured to: control the at least one transmit antenna unit and the at least one receive antenna unit to communicate with at least one first terminal on a first frequency band; control at least one target transmit antenna unit to send a radar signal on a second frequency band; and control at least one target receive antenna unit to receive a first echo signal on the second frequency band. The at least one transmit antenna unit includes the at least one target transmit antenna unit. The at least one receive antenna unit includes the at least one target receive antenna unit. The first frequency band and the second frequency band do not overlap.

Abstract: Embodiments of this application provide a radiation apparatus and a multi-band array antenna, and relate to the field of antenna technologies. The radiation apparatus includes a radiation module, a first conductor balun, and a second conductor balun. The first conductor balun is mechanically connected to the second conductor balun under the radiation module. The radiation module includes a first radiation unit and a second radiation unit in a +45° polarization direction, and a third radiation unit and a fourth radiation unit in a −45° polarization direction. The first conductor balun is configured to feed a first differential signal to the first radiation unit and the second radiation unit. The second conductor balun is configured to feed a second differential signal to the third radiation unit and the fourth radiation unit. The first conductor balun and the second conductor balun are disposed in the same plane.

Abstract: A data processing method and a client is provided. When obtaining a first data packet and a second data packet of a target call service, a client classifies the first data packet into a first data packet set and classifies the second data packet into a second data packet set based on a first time segment and a second time segment, where a first obtaining moment of the first data packet belongs to the first time segment, a second obtaining moment of the second data packet belongs to the second time segment, the first time segment and the second time segment are different time segments. Furthermore, the client calculates, audio and/or video quality corresponding to the first data packet set, and audio and/or video quality corresponding to the second data packet set.
