Title:
BP EQUALIZATION METHOD, DEVICE, COMMUNICATION APPARATUS AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/057798
Kind Code:
A1
Abstract:
Provided are a BP equalization method, device, communication apparatus and storage medium, first, the received signal Yc, the channel estimation Hc, and the symbol estimation Xc are split into the real parts and imaginary parts to obtain the received signal matrix Y, the channel estimation matrix H and the symbol estimation matrix X (S101); then the channel estimation matrix H is subjected to orthogonal triangular QR decomposition to obtain the equivalent received signal Ybp, the equivalent channel R and the noise power σ2 (S102), further, based on the obtained equivalent received signal Ybp, the equivalent channel R, and the noise power σ2, performing iteration to obtain the position probability of each stream symbol (S103).
