Abstract

The invention provides an ad hoc network communication method based on hybrid modulation, and the method employs a LoRa and FSK hybrid modulation mode, transmits wake-up information containing a lead code and a synchronization word through the FSK modulation mode, determines which device needs to be awakened through the judgment of the lead code and the synchronization word. Under the condition that the device needs to be awakened, the LoRa communication mode is switched to perform data interaction, so that the problems of false wake-up and excessive power consumption are avoided.

Description

technical field [0001] The invention belongs to the communication field, and relates to an ad hoc network communication method based on mixed modulation, in particular to an ad hoc network communication method using LoRa and FSK mixed modulation. Background technique [0002] As the infrastructure of the digital economy, the Internet of Things is an important means for the digital transformation of enterprises and an important measure to promote the economic recovery of various countries. The status of the Internet of Things in economic development is constantly improving, and the proportion of the digital economy in the GDP of various countries is also increasing. Increase.
