Abstract

The embodiment of the invention relates to a signal processing method, equipment and device and a computer readable storage medium. The method comprises: at a first device, receiving a signal from a second device; determining a statistical distribution of values of at least one feature of the signal; determining an equalizer parameter corresponding to the signal based on the numerical statistical distribution according to a predetermined model for mapping the numerical statistical distribution to the equalizer parameter; and performing equalization processing on the signal based on the equalizer parameter. According to the scheme provided by the embodiment of the invention, the configuration of the tap coefficient of the signal equalizer in the high-speed PON can be quickly and accurately completed, and the convergence time of adaptive learning of the coefficient can be effectively shortened compared with the existing iterative algorithm.

Description

technical field [0001] Embodiments of the present disclosure relate to the communication field, and more specifically, to a signal processing method, device, device, and computer-readable storage medium. Background technique [0002] In recent years, the high-speed Passive Optical Network (PON) technology with a rate above 10Gbps is the research focus of the International Telecommunication Union Telecommunication Standardization Bureau (ITU-T). High-speed PON aims to provide intensity modulation / direct detection (IM / DD) 25 / 50 Gbps per wavelength service. [0003] In high-speed PON, signal quality can be compromised due to inter-symbol interference (ISI) caused by bandwidth limitations of components at the transmitter and receiver, ISI caused by dispersion in fiber optic transmission, and lack of common equalization configuration for optical network units (ONUs). Deterioration, and even cause the detection of 0 and 1 at the receiving end to fail. Therefore, an improved sign...
