Problems solved by technology

[0002] At present, the general data transmission system on the market uses a fixed frequency band for data transmission. For example, the current common consumer drones use a fixed 2.4G frequency band; in the space environment, there are signal interferences in various frequency bands, so if the If the same frequency band signal appears in the data communication, the equipment is susceptible to interference, which will cause data transmission error or decrease the communication distance. When the interference is strong, the control of the equipment may fail, resulting in damage to the equipment. In severe cases, it may cause danger to personal safety.

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0030] The communication system of the present invention includes a signal transmitting module and a signal receiving module, wherein the signal transmitting module and the signal receiving module communicate through space radio signals, and the signal transmitting module mainly completes external data collection, channel coding, spread spectrum, GMSK modulation and frequency mixing Frequency hopping function; the signal receiving module mainly completes signal mixing frequency hopping, capture, judgment, RS decoding, framing and external data interaction functions. The interrelationships between the modules are as figure 1 shown. The details are as follows.

[0031] The signal transmission module includes:

[0032] The data acquisition module is used to collect information data and send i...

Abstract

The invention provides a communication system and method based on frequency hopping, GMSK and DS, and the method comprises the steps of using a signal transmission module to collect the information data, carrying out the RS coding, DS direct spread and GMSK modulation on the information data, carrying out the frequency mixing and frequency hopping processing, and then transmitting; and using the signal receiving module receives the information data transmitted by the signal transmitting module, perform frequency hopping and mixing processing, then perform capturing, judging, decoding and framing processing, and finally output the information data. Through the RS coding, DS direct spread, GMSK modulation and frequency mixing and frequency hopping processing, the anti-interference capabilitycan be greatly improved, and the safe and accurate transmission of signals is ensured.

Description

technical field [0001] The invention belongs to the communication field, in particular to a communication system and method based on frequency hopping, GMSK and DS. Background technique [0002] At present, the general data transmission system on the market uses a fixed frequency band for data transmission. For example, the current general-purpose consumer drones use a fixed 2.4G frequency band; in the space environment, there are signal interferences in various frequency bands, so if in If the same frequency band signal appears in the data communication, the equipment is susceptible to interference, resulting in data transmission errors or a decrease in the communication distance. When the interference is strong, the control of the equipment may fail, resulting in damage to the equipment. In severe cases, it may cause danger to personal safety. [0003] Therefore, in information transmission, strict requirements are placed on the anti-interference, security and stability of...
