Document Type and Number:
WIPO Patent Application WO/2021/063219
Kind Code:
A1
Abstract:
Provided are a signal sampling method and apparatus, and an optical receiver. The method comprises: sampling a received burst signal according to a first sampling frequency to obtain a first sampled signal; sampling a preamble signal in the first sampled signal according to a second sampling frequency to obtain a second sampled signal; determining the phase difference between the burst signal and a local sampling clock corresponding to the first sampling frequency according to the second sampled signal; and performing interpolation on the first sampled signal according to the phase difference to obtain a target sampled signal.
