Title:
WIRELESS COMMUNICATION SYMBOL DETECTION METHOD AND APPARATUS FOR MULTIPLE-INPUT MULTIPLE-OUTPUT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/031980
Kind Code:
A1
Abstract:
The present disclosure provides a wireless communication symbol detection method and apparatus for a multiple-input multiple-output system. The method comprises: in each communication time block, receiving a first received signal vector set corresponding to supervised identification symbols and a second received signal vector set corresponding to valid data, wherein modulation symbols in a modulation symbol set comprise the supervised identification symbols in a supervised identification symbol set and the remaining modulation symbols; on the basis of the first received signal vector set and the second received signal vector set, estimating target received data centroids corresponding to the modulation symbols in the modulation symbol set; constructing a determination criterion on the basis of mapping relations between the modulation symbols in the modulation symbol set and the target received data centroids; receiving a received signal vector corresponding to a wireless communication symbol to be detected; and determining, on the basis of the determination criterion, the received signal vector corresponding to the wireless communication symbol to be detected, and recovering a wireless communication symbol. The present disclosure can not only improve the detection performance, but also improve the communication efficiency.
