Abstract
Matrix operations are simplified by precalculating and storing certain portions of the operation. This reduces the computational burden, while requiring a modest increase in memory usage. The operations may be performed in a Multiple-Input/Multiple-Output ('MIMO') configuration of an LTE system, where a number of equalizer functions require matrix operations such as derivation of a covariance matrix, which involves matrix multiplication, as do other operations. The operations may be performed on a programmable integrated circuit device configured for that purposes.
