Impact of Imperfect CSI on Capacity of ISI MIMO Systems Based on Joint Precoding and Equalization Designs

It is clear that a channel state information (CSI) influences performance of communication systems. Therefore, researching on impact of the CSI on the system performance and developing new techniques for the state of the art communication systems under different CSI conditions attract the great attention of researchers. In this paper, we analyze the performance of system which shares redundancy and combines designs of precoder and equalizer. Furthermore, the proposed system is evaluated based on imperfect CSI at the receiver and calculation results have proved the strong impact of channel estimation error on the system capacity. © 2019 IEEE.
