A vector-precoding technique known as "vector-perturbation" achieves near-capacity on a multi- antenna multi-user wireless channel. However, the technique currently requires choices for certain regularization and perturbation parameters and these parameters are currently chosen in a rather ad-hoc manner. We analyze the statistical properties of the vector- perturbation scheme and provide guidelines for choosing these parameters in a more systematic manner. These properties suggest that a large… CONTINUE READING
