Title:
SIGNAL PROCESSING METHOD AND APPARATUS, AND PROCESSING CHIP AND SIGNAL TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/011294
Kind Code:
A1
Abstract:
A signal processing method and apparatus, and a processing chip and a signal transmission system. The signal processing apparatus comprises an equalization module, a rough decision module, a filtering module, a maximum likelihood sequence estimation (MLSE) module and a mapping module, wherein the equalization module is used for performing equalization processing on an initial signal to obtain an equalization signal; the rough decision module is used for determining dimension reduction position information and a dimension reduction signal according to the equalization signal, the number of signal states of the dimension reduction signal being less than the number of signal states of the equalization signal, and the dimension reduction signal being unrelated to a modulation format; the filtering module is used for performing filtering processing on the dimension reduction signal to obtain a filtering signal; the MLSE module is used for determining a target path branch of the filtering signal; and the mapping module is used for performing, according to the dimension reduction position information, mapping on the target path branch to obtain a target signal. By means of the present application, the resource consumption of an MLSE module is reduced.
