Abstract
The invention discloses wireless equipment, a signal processing method and a chip, and belongs to the technical field of communication. In the invention, when a radio frequency receiving channel in a signal receiving and transmitting unit receives a signal through an antenna, a radio frequency transmitting channel in the signal receiving and transmitting unit outputs a cancellation signal corresponding to an interference signal, and a signal coupling module is newly added in the signal receiving and transmitting unit of the wireless equipment; and the signal coupling module is used for coupling the cancellation signal output by the radio frequency transmitting channel with the signal received by the antenna so as to eliminate the interference signal in the signal received by the antenna, namely, the self-interference elimination is realized. Therefore, the wireless equipment provided by the invention utilizes the idle radio frequency transmitting channel in the signal receiving and transmitting unit to output the cancellation signal of the interference signal, and compared with the mode that a hardware circuit is newly added to output the cancellation signal, the wireless equipment provided by the invention is relatively low in hardware cost.
