摘要
设计了一种基于FPGA和DSP的光纤信号实时处理系统,介绍了系统的硬件组成和工作原理。该系统采用FPGA实现数据的高速采集和逻辑控制,用DSP实现传感信号的全数字解调,分析了载波相位延迟对解调输出的影响并采取了纠正措施。
A real-time processing system based on FPGA and DSP of optical fiber sensor signal was designed. Hardware constitutes and working principle of the system was introduced. In this system, FPGA is used as a main logic unit and DSP is used as a digital demodulate unit. The influence of carrier phase delay on demodulation output is corrected.
