Title:
閉ループ多入力多出力システムにおけるプレコーディングマトリックスの選択方法及び選択システム
Document Type and Number:
Japanese Patent JP5537725
Kind Code:
B2
Abstract:
A method and a system for selecting a pre-coding matrix in a closed loop MIMO system are provided. The method includes: traversing all pre-coding matrices and respectively calculating a CINR corresponding to each pre-coding matrix; and obtaining an MCS according to a CINR corresponding to a pre-coding matrix, calculating a spectral efficiency corresponding to the MCS, and selecting a pre-coding matrix with a largest spectral efficiency. According to the method and system provided by the present disclosure, an appropriate pre-coding matrix can be selected. By using the appropriate pre-coding matrix in the closed loop MIMO system, the channel quality, the throughput of a closed loop multiplexing system in the scenario that the channel changes slowly, and the gain can be improved. Besides, the method of the present disclosure can avoid calculation of the BER formula on the premise of a large number of assumptions, and reduce the computation complexity.
