Abstract

The present invention relates to a wireless communication method and system, which solves the technical problems of low confidentiality and low efficiency. By adopting a transmitter including a baseband coding unit for converting data into a baseband coding signal, a central unit connected to the baseband coding unit A processor, a modulation module connected to the central processing unit and at least 2 laser modules; each laser module is provided with an identification code, and also includes a timing unit and a temperature detection unit; the central processing unit is based on the timing parameters of the timing unit and the temperature detection unit The temperature parameter selects one of the laser modules as the laser emission module, and controls the laser emission module to send out laser signals according to the encoding result received from the modulation module; the modulation module includes multiple modulation subunits, each modulation subunit corresponds to a modulation method, and the modulation module The technical solution of selecting the corresponding modulation sub-unit according to the modulation identification code of the central processing unit solves this problem better and can be used in wireless communication.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a wireless communication method and system. Background technique [0002] Wireless communication mainly includes microwave communication, laser communication and satellite communication. Microwave is a kind of radio wave, and its transmission distance is generally only tens of kilometers. But the frequency band of microwave is very wide, and the communication capacity is very large. For microwave communication, a microwave relay station needs to be built every tens of kilometers. Satellite communication is the use of communication satellites as relay stations to establish microwave communication links between two or more earth stations on the ground or between mobile bodies. Laser communication is a communication method that uses laser light to transmit information. Laser is a new type of light source, which has the characteristics of high brightness, strong dire...
