可见光通信的小区分布可以通过复用光谱来提高数据传输能力。在本文中，我们对相邻单元A、B和C分别采用了OOK、PPM和PWM三种调制格式。样机实验结果表明，采用本方案可以实现1.0 Mbit/s和6.25 Mbit/s的可见光通信系统的无差错传输。利用可用的LED，我们可以预期具有无缝连接的可见光通信系统的数据速率可高达71.4 Mbit/s。
Cells distribution for visible light communication can enhance the capacity of the data transmission by the reuse of optical spectrum. In this paper, we adopt three modulation formats as OOK, PPM and PWM for neighboring cells A, B and C respectively. The prototype experiment results demonstrate the error free transmission of 1.0 Mbit/s and 6.25 Mbit/s visible light communication system with our scheme. With the available LED, we can expect that the data rate of a visible light communication system with seamless connectivity can be up to 71.4 Mbit/s.
