摘要： A wireless device and a wireless local area network (WLAN) signal receiving method, where the wireless device includes a receiver, a jamming circuit, an interference cancelling circuit, a first antenna, and a second antenna. The receiver is coupled to the first antenna and configured to detect a WLAN signal, the jamming circuit is coupled to the second antenna, an input end of the interference cancelling circuit is coupled to the second antenna, and an output end of the interference cancelling circuit is coupled to the first antenna. The jamming circuit is configured to send, using the second antenna, an interference signal on a channel on which the WLAN signal is located, and the interference cancelling circuit is configured to generate, based on the interference signal, a reconstruction signal cancelling the interference signal received by the first antenna, and provide the reconstruction signal at the output end.
