A high speed UV communication method and system
摘要
针对低重频光源要实现高码率数据传输的问题,采用紫外激光器作为光源,研究了4-PPM调制解调算法,在FPGA上实时实现该算法,并由此构建了一套基于紫外激光器的紫外光通信系统。外场通信实验表明,在紫外激光器脉冲重复频率为20kHz的条件下,通信系统可实现码率高达40kbit/s的数据传输,误码率优于10-4。
Abstract
An ultraviolet communication system based on ultraviolet (UV) laser and the 4-PPM modulation and demodulation algorithm implemented by FPGA in real time are constructed. The field experiments show that the transmission rate of 40kbit/s and the bit error rate less than 10-4 are realized in the communication system with the UV laser pulse repetition frequency of 20 kHz.
