Abstract

The disclosure relates to a matrix inversion method, device, device and storage medium for a multi-antenna system, and relates to the field of wireless communication technology. The method includes: obtaining the interference noise covariance matrix in the multi-antenna system, the interference noise covariance matrix is a fourth-order square matrix determined based on the noise sequences of four receiving antennas in a multi-antenna system. The two elements in the interference noise covariance matrix that are symmetrical along the main diagonal are conjugate equal; the interference noise covariance matrix is ​​decomposed into Four sub-matrices, each sub-matrix is ​​a second-order square matrix; based on the four sub-matrices, the inverse calculation of the interference noise covariance matrix is ​​performed to determine the inversion result of the interference noise covariance matrix. In this way, the fourth-order interference noise covariance matrix can be decomposed and reduced. Since the process of layer-by-layer iteration is omitted and the inversion result can be obtained directly, the loss of accuracy in the iterative process can be avoided, making the bit error in the multi-antenna system The rate is reduced, and the amount of calculation is reduced at the same time.

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...
