Distributed CSI Acquisition and Coordinated Precoding for TDD Multicell MIMO Systems

Several distributed coordinated precoding methods exist in the downlink multicell multiple-input-multiple-output (MIMO) literature, many of which assume perfect knowledge of received signal covariance and local effective channels. In this paper, we let the notion of channel state information (CSI) e...
