Multi-Tap DFE with State-Tracking Demapper for IM-DD Systems
We propose a multi-tap DFE with state tracking demapper (DFE-STD) to improve the LLR accuracy. The experimental results show that the DFE-STD achieves a gain of 3.17 dB for post-FEC at BER of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1\times 10^{-5}$</tex> compared to the traditional DFE. © 2024 The Author(s)
