Digital signal processing algorithms for optical communications

We propose low resolution digital pre-compensation to enhance DAC effectiveness for photonic terahertz communications, and our experiment with 16 Gbit/s PAM4 signals at 150GHz shows a ~4 dB SNR improvement using a 3-bit resolution DAC.
