摘要：
In this paper we investigate the design of a robust MMSE linear precoding Multiuser Multiple Input Single Output (MU MISO) system with limited feedback that exploits multiple feedback vectors to improve the quality of the available CSI at transmission. We explain how to appropriately exploit this additional past channel information to design the channel estimator, rank basis reduction and the quantizer parameters.
