Abstract
Disclosed herein are lattice reduction systems and methods for a MIMO communication system. One such method includes providing a channel matrix corresponding to a channel in a MIMO communication system, preprocessing the channel matrix to form at least an upper triangular matrix, implementing a relaxed size reduction process, and implementing a basis update process. Implementing the relaxed size reduction process comprises choosing a first relaxed size reduction parameter for a first-off-diagonal element of the upper triangular matrix, choosing a second relaxed size reduction parameter, which is greater than the first relaxed size reduction parameter, for a second-off-diagonal element of the upper triangular matrix evaluating whether a first relaxed size reduction condition is satisfied for the first-off-diagonal element of the upper triangular matrix, and evaluating whether a second relaxed size reduction condition is satisfied for the second-off-diagonal element of the upper triangular matrix.
