Title:
LARGE-DIMENSIONAL COMMUNICATION SIGNAL PROCESSING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/027321
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of wireless communications. Disclosed are a large-dimensional communication signal processing method and apparatus, and an electronic device. The method comprises: signal grouping, i.e. performing arrangement and combination on symbols in a signal to be subjected to error correction having the length of N, so as to obtain Cn
N symbol groups to be subjected to error correction; error correction sorting, i.e. determining the error correction sequence of said symbol groups according to the descending order of two-norms of residual vectors corresponding to said symbol groups; symbol group error correction, i.e. sequentially updating said symbol groups according to the error correction sequence, thereby completing one round of signal error correction; and iteration selection, i.e. comparing two-norms of a residual of the signal in the current round with two-norms of a residual corresponding to the signal in the previous round, if the difference between the two is less than a set threshold value, completing the symbol error correction, otherwise, increasing the length of a symbol group, starting the next round of iteration processing until the residual is unchanged, and ending the error correction. The present invention can solve the problem of traditional large-dimensional signal detection having high complexity and a high bit error rate.
