Abstract
Various aspects of the present disclosure generally relate to wireless communication. Various aspects relate generally to determining information metrics associated with an eigenvalue decomposition (EVD) operation associated with a four by four Hermitian matrix. Some aspects more specifically relate to determining a scalar (e.g., an eigenvalue or an approximation of an eigenvalue) of the four by four Hermitian matrix and determining a shifted matrix by subtracting a product of the scalar and an identity matrix from the four by four Hermitian matrix. A QR decomposition may be performed on the shifted matrix to determine first derived information, representable by a three by three Hermitian matrix. An eigenvalue decomposition operation may be performed on the three by three Hermitian matrix to determine the eigenvalues and eigenvectors of the four by four Hermitian matrix.
