Abstract

The invention relates to a wireless communication method and system, and aims to solve the technical problems of low confidentiality and low efficiency. A transmitter comprises a baseband coding unitfor converting data into a baseband coding signal, a central processing unit connected with the baseband coding unit, a modulation module connected with the central processing unit, at least two lasermodules, a timing unit and a temperature detection unit, wherein each laser module is provided with an identification code; the central processing unit selects one of the laser modules according to timing parameters of the timing unit and temperature parameters of the temperature detection unit to serve as a laser transmitting module; the laser transmitting module is controlled to transmit a laser signal according to a coding result from the modulation module; the modulation module comprises a plurality of modulation sub-units; each modulation sub-unit corresponds to one modulation method; and the modulation module chooses a corresponding modulation sub-unit according to a modulation identification code of the central processing unit. Through adoption of the wireless communication methodand system, the problem is well solved. The wireless communication method and system can be applied to 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...
