Abstract

The invention relates to a matrix inversion method, device and equipment for a multi-antenna system and a storage medium, and relates to the technical field of wireless communication, and the method comprises the steps: obtaining an interference noise covariance matrix in the multi-antenna system, wherein the interference noise covariance matrix is a four-order square matrix determined based on noise sequences of four receiving antennas in the multi-antenna system, and two elements symmetrical along a main diagonal in the interference noise covariance matrix are conjugated and equal; decomposing the interference noise covariance matrix into four sub-matrixes, wherein each sub-matrix is a second-order square matrix; and performing inversion calculation on the interference noise covariance matrix based on the four sub-matrixes, and determining an inversion result of the interference noise covariance matrix. In this way, decomposition and order reduction can be carried out on the four-order interference noise covariance matrix, and the inversion result can be directly obtained by omitting the layer-by-layer iteration process, so that the precision loss in the iteration process can be avoided, the bit error rate in the multi-antenna system is reduced, and meanwhile, the operand is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a matrix inversion method, device, device and storage medium for a multi-antenna system. Background technique [0002] In the field of wireless communication technology, the receiving end in a multi-antenna system will involve a large number of matrix inversion operations. For example, in the Interference Rejection Combining (IRC) algorithm, it is necessary to The variance matrix Ruu (Ruu is the correlation matrix of noise and interference and vector) is inversely calculated, and the inversion result of the interference noise covariance matrix Ruu will directly affect the accuracy of the IRC algorithm. In related technologies, common methods for obtaining the inversion result of the interference noise covariance matrix Ruu include cholesky decomposition and inversion method and circular labeling method. Among them, the cholesky decomposition and inver...
