Abstract

The invention discloses an optical communication method, device and system. The problems that optical communication alignment is difficult, communication link quality is unstable and optical mimo power consumption is high are comprehensively solved by comprehensively utilizing an optical mimo technology, a wake-up technology containing sequential control and an incoming light direction estimationand tracking and multi-path combination technology. The scheme comprises the following steps: determining an optical communication direction according to a received first signal; determining at leastone target light receiving device and at least one target light sending device; and waking up the at least one target light receiving device in the dormant state and the at least one target light sending device in the dormant state, and performing optical signal communication of optical alignment with an opposite end sending the first signal through the optical communication direction. According to the scheme, optical signal receiving and transmitting can be performed directionally, the wireless optical signal communication stability is improved, and the overall communication power consumptionis reduced.

Description

technical field [0001] The present invention relates to the field of optical communication, and in particular, to an optical communication method, device and system. Background technique [0002] Wireless optical communication, also known as wireless optical signal communication, is a method of communication through optical signals, which has the advantages of high speed, convenient spatial multiplexing, high security, and strong anti-interference. However, there are disadvantages such as strong optical signal transceiver directionality, and optical signal transceiver devices need to be aligned with each other. In some application scenarios, the optical path of the optical signal may be deflected, resulting in fluctuations and fading of the received signal, and even communication interruption. [0003] In a multiple-in multiple-out (MIMO) system, multiple antennas are used at both the transmitting end and the receiving end, which is an antenna system that forms multiple cha...
