A communication system and method based on frequency hopping, gmsk and ds

Abstract

The present invention provides a communication system and method based on frequency hopping, GMSK and DS. The signal transmission module collects information data, performs RS coding, DS direct spread and GMSK modulation processing on the information data, and then performs frequency mixing and frequency hopping processing before transmitting ; The signal receiving module receives the information data transmitted by the signal transmitting module and performs frequency hopping and mixing processing, and then performs capture, judgment, decoding and framing processing, and finally outputs the information data. By adopting RS coding, DS direct expansion, GMSK modulation and frequency mixing and frequency hopping processing, the present invention can greatly improve anti-interference ability and ensure safe and accurate signal transmission.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a communication system and method based on frequency hopping, GMSK and DS. Background technique [0002] Currently, common data transmission systems on the market use fixed frequency bands for data transmission. For example, currently common consumer drones all use fixed 2.4G frequency bands; When signals of the same frequency band appear in data communication, the equipment is susceptible to interference, which will cause data transmission errors or decrease the communication distance. When the interference is strong, the control of the equipment may fail, resulting in damage to the equipment and, in severe cases, danger to personal safety. [0003] Therefore, in information transmission, severe requirements are put forward for the anti-interference, security and stability of communication, which has become an important problem in current wireless communication equipment...

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.
