摘要
In order to control the inter-cell interference for a multi-cell multi-user
multiple-input multiple-output network, we consider the precoder design for
coordinated multi-point with downlink coherent joint transmission. To avoid
costly information exchange among the cooperating base stations in a
centralized precoding scheme, we propose a decentralized one by considering the
power minimization problem. By approximating the inter-cell interference using
the deterministic equivalents, this problem is decoupled to sub-problems which
are solved in a decentralized manner at different base stations. Simulation
results demonstrate the effectiveness of our proposed decentralized precoding
scheme, where only 2 7
optimal centralized precoder.
