Low Resolution Digital Pre-Compensation for Photonic Terahertz 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 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\sim 4 ~\text{dB}$</tex> SNR improvement using a 3-bit resolution DAC.
