An Efficient Precoder Design for Multiuser MIMO Cognitive Radio Networks With Interference Constraints

We consider a linear precoder design for an underlay cognitive radio multiple-input multiple-output (MIMO) broadcast channel, where the secondary system consisting of a secondary base station (BS) and a group of secondary users is allowed to share the same spectrum with the primary system. All the t...
