Abstract
A radio frequency (RF) front-end system and a method for reducing interference are provided. The RF front-end system includes a processing circuit, a first transceiver, an RF front-end circuit, and a first antenna. The RF front-end circuit includes a first switch circuit, a first filter circuit, and a second switch circuit. The first switch circuit and the second switch circuit respectively include first signal paths and second signal paths. The first filter circuit includes an all-pass circuit corresponding to a first frequency band and a first channel filter corresponding to a first frequency channel. The processing circuit executes an anti-interference process, including: switching to the all-pass circuit; executing a channel sounding process to determine usage statuses of a plurality of channels; executing an automatic channel selection process to select a target channel; and switching to the target channel, and controlling the first transceiver to perform signal transmission.
