Title:
HYBRID SOFT INFORMATION-AIDED BLOCK LINEAR EQUALIZER, AND BIDIRETIONAL BLOCK LINEAR EQUALIZER
Document Type and Number:
WIPO Patent Application WO/2022/037021
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communications, and relates in particular to a hybrid soft information-aided block linear equalizer (HBLE), and a bidiretional block linear equalizer. The block linear equalizer uses an a priori decision corresponding to a non-estimated symbol and an a posteriori decision for an estimated symbol so as to obtain an estimation symbol, and each time an a priori decision corresponding to a non-estimated symbol and an a posteriori decision for an estimated symbol are used to obtain an estimation symbol, the mean of preprocessing vectors is calculated, and a fixed covariance matrix is used when calculating each unknown symbol. In the present invention, when the number of unknown symbols is large, LC-HBLE and Bi-LC-HBLE equalizers can be used to reduce computational complexity, and when the number of unknown symbols is small, Bi-HBLE and HBLE equalizers can improve performance.
