Preamble Design for Online IQ Skew Estimation in Burst-mode DSP for 400G Coherent TFDM-PON Upstream
We report a fast transceiver online IQ-skew estimation method with special designed preamble in upstream burst-mode DSP, achieving transceiver estimation errors within ±0.3 ps after average operation in the 400G coherent TFDM-PON upstream.
