Low-complexity PAPR Reduction based on Partial Transmit Subcarrier Technology in 400G Coherent TFDM PON
We propose and demonstrate a low-complexity downstream signal peak-to-average power ratio (PAPR) reduction scheme based on partial transmit subcarrier technology for 400G coherent time-and-frequency-division PON. Experimental results show our approach provides over 1dB power-budget improvement. © 2025 The Author(s)
