二十一世纪进入了信息化时代,网络通信也广泛运用在人们的生活中以及社会发展的方方面面。随着通信用户的增加,所使用和占用的电磁波带也越发显得拥挤起来。由此为了提高通信系统的运作效率和技术,提高频带宽度、扩大通信容量、提高传输速度等等都成了眼下急需解决的问题。本篇文章就将对可见光通信系统的关键技术展开研究。 The 21st century has entered an era of information. Network communications are also widely used in people’s lives and in all aspects of social development. With the increase of communication users, the electromagnetic bands used and occupied become more and more crowded. Therefore, in order to improve the operation efficiency and technology of the communication system, increasing the bandwidth, expanding the communication capacity, increasing the transmission speed and the like have all become urgent problems to be solved. This article will study the key technologies of visible light communication system.
