Claim 28:
29. An apparatus for wireless communication at a first device, comprising:
means for obtaining one or more of data or at least one signal associated with at least one first matrix, wherein the at least one first matrix is at least one square matrix, such that a length of the at least one first matrix is equal to a width of the at least one first matrix;
means for performing a decomposition process on the at least one first matrix to obtain at least one first triangular matrix;
means for normalizing, based on the decomposition process, the at least one first triangular matrix to obtain at least one second triangular matrix;
means for estimating at least one of: (1) an inverse of the at least one second triangular matrix, or (2) an inverse of the at least one first triangular matrix based on the at least one second triangular matrix;
means for calculating an inverse of the at least one first matrix based on at least one of: (1) the estimated inverse of the at least one second triangular matrix, or (2) the estimated inverse of the at least one first triangular matrix; and
means for transmitting the one or more of the data or the at least one signal based on the calculated inverse of the at least one first matrix.
