Abstract

In this paper, we propose a decentralized cooperative precoding scheme in multi-cell MIMO system. In the proposed scheme, each user feeds back its CSI to all neighboring BSs. BS uses the CSI to generate its precoding vector independently. Three iterative updating transceiver design algorithms are proposed. Simulation results show their effectiveness.
