Abstract
Methods and apparatus for fast Eigenvalue decomposition of Hermitian matrices are disclosed. In an exemplary embodiment, a method is provided for performing a decomposition iteration that includes identifying a largest off-diagonal term of a channel response matrix, generating a 2×2 Hermitian matrixthat includes the largest off-diagonal term, and generating a 2×2 Unitary matrix Ūfrom the 2×2 Hermitian matrix. The decomposition iteration also includes multiplying the 2×2 Unitary matrix Ūwith the 2×2 Hermitian matrixto generate an updated largest off-diagonal term and updating the channel response matrixwith the updated largest off-diagonal term. The method also includes performing one or more additional decomposition iterations until all off-diagonal terms of the channel response matrixare less than a target value.
