Abstract

The invention provides a full-duplex transceiver, electronic equipment and an interaction method. The full-duplex transceiver comprises at least one transmitting line, at least one receiving line andan analog elimination module; for any pair of transmitting line and receiving line, the analog elimination module is connected with the receiving line and the transmitting line and is used for carrying out analog elimination on the self-interference signal in the received signal according to the transmitting signal. Compared with the prior art, the full duplex transceiver provided by the inventioncan better suppress the self-interference from the transmitting line to the receiving line of the same equipment caused by full duplex communication, and achieve the reasonable compromise between theself-interference suppression performance and the implementation complexity.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular, the present application relates to a full-duplex transceiver, electronic equipment and an interaction method. Background technique [0002] According to ITU estimates, by 2020, the global monthly mobile data traffic will reach 62 exabytes (Exa Byte, 1EB=2 30 GB), and from 2020 to 2030, the global mobile data service will grow at an annual rate of about 55%. In addition, the proportion of video services and machine-to-machine communication services in mobile data services will gradually increase. In 2030, video services will be 6 times that of non-video services, and machine-to-machine communication services will account for 12% of mobile data services. %about. [0003] The rapid growth of mobile data services, especially the exponential growth of high-definition video and ultra-high-definition video services, puts forward higher requirements on the t...
