Abstract：In the case of the delay and error Channel State Information (CSI),a robust joint interference and phase alignment algorithm based on Bayes estimation and power allocation among signal flows is proposed for multi-cell MIMO-BC.Firstly,the best prediction of the current CSI is obtained through Bayes estimation by the senders.Secondly,interference suppression matrix is designed through maximizing signal to inter-cell interference plus noise ratio in the forward link,and the pre-coding matrix is designed through maximizing SINR in the reverse link.Further,the water-filling power allocation is used to optimize power allocation among signal flows.Finally,the interference among the data flows is rotated into signal space which improves the received power.Under the conditions of the perfect CSI and the delay and error CSI,the simulation results verify that the proposed algorithm improves the performance of system compared with the existing algorithms.
