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.

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: Provided is a method for automatically generating a banner image for a promotion, performed by a computing device comprising a processor and a memory. The method comprises the steps of: acquiring information about any concept classification to which a product or service to be promoted corresponds from among a plurality of predefined concept classifications; determining a setting value for a foundation that is a minimum unit constituting the design of a banner image, on the basis of the concept classification to which the product or service to be promoted belongs; determining at least one component included in the banner image, on the basis of the setting value for the foundation; and generating at least one banner template including component arrangement information that is information about the location and size of which of the at least one component.

Abstract: An analog predistorter (APD) core module including a radio frequency delay module, an envelope module, and a contact matrix module. The radio frequency delay module is configured to receive a feed-forward radio frequency signal, generate multiple radio frequency delay signals with different delays according to the feed-forward radio frequency signal, and output each radio frequency delay signal to the contact matrix module. The envelope module is configured to receive the feed-forward radio frequency signal, perform envelope detection on the feed-forward radio frequency signal to obtain multiple envelope signals with different delays, and output each envelope signal to the contact matrix module. The contact matrix module is configured to receive each radio frequency delay signal, each envelope signal, and a predistortion coefficient from an exterior source, and generate a predistortion signal according to the predistortion coefficient, each radio frequency delay signal, and each envelope signal.
