提出并论证了一种基于数字信号处理的强度调制模拟链路三阶互调失真抑制新技术。在该方案中，我们可以根据实际情况动态地获得非线性补偿函数。实验上，已经实现了超过20dB的IMD3抑制。
A novel technique to suppress the third-order intermodulation distortion (IMD3) in intensity-modulated analog links based on digital signal processing is proposed and demonstrated. In this scheme, we can dynamically obtain the nonlinear compensation function according to the actual situation. Experimentally, more than 20dB suppression of IMD3 has been achieved.
