Shrnutí:A novel generalized side-information cancelling precoder is proposed for the multiuser MIMO downlink systems over MIMO broadcast fading channels. The proposed transceiver involves the following stages. First, the minimum mean square error (MMSE) based channel inversion (MMSE-CI) technique is utilized to suppress multiuser broadcast interference. Next, using the generalized side-information cancellation (GSIC) technique, it can further reduce the residual multiuser interference and the noise, which is induced by MMSE-CI preprocessing. Finally, using the singular value decomposition method, the spatial streams interference of each user is suppressed by the preprocessing and post-processing eigenvector matrices. Furthermore, the proposed precoder can be easily extended to incorporate the water filling and diagonal loading methods for the performance enhancement of the overall system. Simulation results show that the proposed GSIC precoder, which offers a better performance, can outperform the conventional precoders. Besides, simulation results confirm that the proposed GSIC precoder with water filling and diagonal loading techniques also exhibits excellent performance.
