摘　　要：阐述了CO-OFDM和DSP的基本原理,利用Opti System和Matlab软件设计了基于DSP的高速实时信号处理研究平台,实现了100Gb/s DP-QPSK系统的单模光纤传输实验。利用DSP模块对接收信号进行处理,结果表明DSP在高速信号处理的精准性、实时性具有很大的潜力,DSP处理后的星座图非常理想,数据传输误码率接近为零。The basic principles of CO-OFDM and DSP are demonstrated. High-speed real-time signal process- ing platform is established based on OptiSystem and Matlab sotlware. The 100Gb/s DP-QPSK experiment in single-mode fiber transmission is accomplished. With the help of DSP module for processing of the received signal, the last constellation is ideal and data transmission error rate is close to zero. The simulation shows a powerful potential application of DSP in the high-speed signal processing.
