Abstract

Methods and apparatus for sub-block based architecture of Cholesky decomposition and channel whitening. In an exemplary embodiment, an apparatus is provided that parallel processes sub-block matrices (R, R, and R) of a covariance matrix (R) to determine a whitening coefficient matrix (W). The apparatus includes a first LDL coefficient calculator that calculates a first whitening matrix W, lower triangle matrix L, and diagonal matrix Dfrom the sub-block matrix R, a first matrix calculator that calculates a lower triangle matrix Lfrom the sub-block matrix Rand the matrices Land D, and a second matrix calculator that calculates a matrix X from the matrices Dand L. The apparatus also includes a matrix subtractor that calculates a matrix Z from the matrix X and the sub-block matrix R, a second LDL coefficient calculator that calculates a third whitening matrix W, lower triangle matrix L, and a diagonal matrix Dfrom the matrix Z, and a third matrix calculator that calculates a second whitening matrix Wfrom the matrices L, L, L, and D.
