Robust Cooperative Nonlinear Transceiver Design in Multi-Party MIMO Cognitive Radio Networks With Stochastic Channel Uncertainty

The problem of robust joint nonlinear transceiver design in a multiuser MIMO interfering Cognitive Radio Network (CR-Net) is studied in this paper. Because of the nonlinear nature of the pre-coding and equalizing schemes, the transmit or receive parties need to be fed back with some information from the other peers, which gives rise to the concept of the cooperation between the transmission peers. This network is a general multi-party network having all the links interfering with each others. It is also assumed that the Channel State Information (CSI) in this network for all the relevant channels is imperfectly known. The CSI is subject to a Stochastic Error (SE) model-based uncertainty. The design procedure is aiming to satisfy the average performance measures.
