The invention discloses a wireless signal processing method and device. The method mainly comprises the following steps: receiving a wireless signal; pre-demodulating the received wireless signal so as to judge whether the received wireless signal belongs to a set modulation mode or not; carrying out complete demodulation on the wireless signal which is judged to belong to the set modulation modeto obtain a demodulated signal; performing protocol preprocessing on the demodulated signal to judge whether a wireless protocol adopted by the demodulated signal belongs to a set wireless protocol ornot; and performing protocol conversion and forwarding on the demodulation signal which is judged to belong to the set wireless protocol. According to the invention, means of pre-demodulation and protocol preprocessing are used to improve the wireless signal demodulation and protocol conversion efficiency; under the condition that wireless signals of multiple modulation modes and wireless protocols exist in an application scene, the set modulation modes and wireless signals of the wireless protocols can be rapidly identified, protocol conversion is achieved, and the information forwarding efficiency of the wireless signals is improved.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless signal processing method and device. Background technique [0002] The signal transmission of wireless sensor network equipment, smart wearable equipment, smart home and other equipment is based on wireless communication technology. There are multiple communication protocols and specifications in wireless communication technology. For example, for Bluetooth, Wi-Fi, ZigBee, Tread, and 802.15.4 custom protocols that support 2.4GHz, various protocols and specifications are not compatible with each other. It is difficult to fundamentally improve the phenomenon that communication protocols cannot coexist. [0003] In an application scenario, terminal devices supporting various communication protocols need to exchange information with the gateway, and the gateway needs to upload the information of the terminal device to the network side, and then use ...
