  • Publication number: 20180294852
    Abstract: A method, a communication device and a communication system for multiple-input-multiple-output (MIMO) communication. In the method, Antenna information and channel information of the communication device are obtained. Eigenvalues of an intermediate matrix according to the antenna information and the channel information are determined, where the intermediate matrix is related to an L-term approximated matrix for Neumann series expansion of a matrix inversion, the matrix inversion is an inverse of a K×K matrix, L is a positive integer, and K is a positive integer according to the antenna information. Coefficients of the L-term approximated matrix are determined from the eigenvalues of the intermediate matrix by calculating a coefficient approximation. The matrix inversion according to the L-term approximated matrix with the determined coefficients of the L-term approximated matrix are determined.
