Embodiment 1

[0039] A wireless communication anti-jamming method, specifically comprising the following steps:

[0040] Step 1. Data synchronization: The communication sender sends communication information for debugging through spread spectrum technology, and modulates the information data with a certain signal bandwidth to be transmitted with a high-speed pseudo-random code whose bandwidth is much larger than the signal bandwidth, so that the original data signal The bandwidth is expanded, then modulated by the carrier and sent out, and the designated receiving end uses exactly the same pseudo-random code to perform correlation processing with the received bandwidth signal, and replace the broadband signal with the narrowband signal of the original information data to obtain communication information for debugging. as a comparative reference;

[0041] Step 2. Interference judgment: After the debugging of step 1 is completed, the communication sending end and the designated receiving end ...

Embodiment 2

[0046] This embodiment, as an improvement of the previous embodiment, is a wireless communication anti-jamming method, which specifically includes the following steps:

[0047] Step 1. Data synchronization: The communication sender sends communication information for debugging through spread spectrum technology, and modulates the information data with a certain signal bandwidth to be transmitted with a high-speed pseudo-random code whose bandwidth is much larger than the signal bandwidth, so that the original data signal The bandwidth is expanded, then modulated by the carrier and sent out, and the designated receiving end uses exactly the same pseudo-random code to perform correlation processing with the received bandwidth signal, and replace the broadband signal with the narrowband signal of the original information data to obtain communication information for debugging. The data synchronization method also includes generating an identifying data transmission code at both the...

Abstract

The invention discloses a wireless communication anti-interference method and a wireless communication module. The wireless communication anti-interference method specifically comprises the following steps: step 1, data synchronization; 2, interference judgment; step 3; 4, performing frequency hopping transmission; and step 5, resetting and debugging. The invention relates to the technical field of wireless communication. According to the wireless communication anti-interference method and the wireless communication module, communication information is collected in different time periods, the problem of different interference degrees due to different time periods is effectively avoided, the same communication data is synchronized in advance, and then the integrity rate of communication data transmission under different carrier frequencies is counted in a mode of transmission with different carrier frequencies; the interference degree of the corresponding carrier frequency of the corresponding region is judged, a plurality of carrier frequencies with low interference degree are screened out to serve as the frequency hopping range, effective interference resistance during communication transmission of the corresponding region is achieved with low cost, self-adaptive adjustment of the carrier frequency is effectively guaranteed under the setting of reset debugging, and then self-adaptive adjustment of the frequency hopping range during frequency hopping transmission is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless communication anti-jamming method and a wireless communication module. Background technique [0002] There are a lot of interference in wireless communication, including the following three types: same-frequency interference, adjacent-frequency interference and intermodulation interference. In order to reduce or avoid interference, multiple input and multiple output wireless transmission technology, virtual smart antenna technology and spread spectrum technology are often One of the three technologies of frequency hopping and frequency hopping technology to reduce or avoid interference. Among them, for frequency hopping technology, the radio transmission frequency technology that hops back and forth according to a specific speed and law is the key to frequency hopping communication. Frequency hopping The technology adopts multi-frequency frequency shift ...
