Title:
SELF-ADAPTIVE EQUALIZATION METHOD AND DEVICE, AND EQUALIZER
Document Type and Number:
WIPO Patent Application WO/2017/215411
Kind Code:
A1
Abstract:
Provided are a self-adaptive equalization method and device, and an equalizer, which relate to the field of communications. The self-adaptive equalization method comprises: acquiring frame positioning information about polarization state data output by an equalizer and a tap coefficient updated after blind equalization processing; according to the frame positioning information and performance information about the equalizer, determining a current operating state of the equalizer; according to the current operating state of the equalizer and the tap coefficient updated after blind equalization processing, correspondingly adjusting the tap coefficient or a leakage factor in blind equalization processing; and according to the adjusted tap coefficient or leakage factor, performing self-adaptive convergence until the equalizer operates stably in a stable state. The solution of the disclosure solves the problem in an existing technical solution that the efficient and stable operation of a self-adaptive equalizer cannot be realized during a convergence process.
