Embodiment Construction

[0114] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0115] Figure 1A is a schematic structural diagram of a communication system provided by an embodiment of the present disclosure, see Figure 1A , the communication system includes: a wireless access point 101 and a plurality of STAs 102, and each STA 102 is connected to the wireless access point 101 through a wireless network.

[0116] Each STA 102 can send a wireless local area network signal, and the wireless access point 101 receives and processes the wireless local area network signal. Alternatively, the wireless access point 101 may also send a wireless local area network signal, and the STA 102 receives and processes the wireless local area network signal. The wireless local area network signal may be a signal carrying an u...

Abstract

The invention provides wireless equipment and a wireless local area network signal receiving method, and belongs to the technical field of communication. Wherein the wireless device comprises a receiver, a jammer, an interference eliminator, a first antenna and a second antenna, the receiver is connected with the first antenna, the jammer is connected with the second antenna, the input end of theinterference eliminator is connected with the second antenna, and the output end of the interference eliminator is connected with the first antenna; The receiver is used for detecting a wireless localarea network signal; The jammer is used for sending an interference signal on a channel where the wireless local area network signal is located through the second antenna; And the interference eliminator is used for generating a reconstructed signal for cancelling the interference signal received by the first antenna based on the interference signal, and providing the reconstructed signal at theoutput end, so that the conflict of the signals of the wireless local area network is avoided, and no extra air interface resource is occupied. And moreover, the interference to the receiver can be eliminated in the process of sending the interference signal, so that the receiver can normally receive the wireless local area network signal.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a wireless device and a wireless local area network signal receiving method. Background technique [0002] Wireless communication technology can connect terminals such as personal computers and mobile phones wirelessly, which brings great convenience to people's life, and has been widely used at present. [0003] A wireless local area network (English: wireless local area network, WLAN) is often used in a short-distance coverage scenario. The WLAN includes a wireless access point (English: access point, AP) and a station (English: station, STA). When one STA transmits a signal, other STAs can hear the signal. The STA that hears the signal determines that the channel is busy and keeps silent. The AP can normally receive the signal sent by the STA. [0004] However, if the distance between STAs is relatively long or there is shielding between STAs, the STA...
