Abstract

The present invention provides a signal processing device, a signal processing method and a mobile terminal, which relate to the technical field of communication and are used to solve the problem that a mobile terminal cannot normally use WiFi in a multi-WiFi scene. The signal processing device of the present invention includes: a first signal receiving module for receiving WiFi signals; a second signal receiving module for receiving LTE signals; a signal detection module for detecting the work of the WiFi signals received by the first signal receiving module frequency band and the working frequency band of the LTE signal received by the second signal receiving module; the signal filtering module is used to filter the WiFi signal received by the first signal receiving module according to the working frequency band of the LTE signal obtained by the signal detection module; The working frequency band of the WiFi signal obtained by the signal detection module filters the LTE signal received by the second signal receiving module. The present invention is mainly used in mobile terminals.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a signal processing device, a signal processing method, and a mobile terminal. Background technique [0002] Data traffic used in a mobile terminal is generally obtained through a cellular network or a wireless local area network (Wireless Local Area Networks, WLAN). In fact, many WLAN signals are converted from cellular network signals, such as WiFi (Wireless Fidelity, Wireless Fidelity) modems. [0003] Currently commonly used WiFi signals include 2.4G WiFi, 5G WiFi, etc., among which 2.4G WiFi is more common. The working frequency band of 2.4G WiFi signal is 2.4Ghz-2.5GHz, with a total of 14 channels. Taking LTE (Long Term Evolution, long-term evolution) as an example, since some operating frequency bands of LTE signals are close to those of 2.4G WiFi, when converting cellular network signals into WiFi signals, LTE signals and WiFi signals...
