Joint and distributed linear precoding for centralised and decentralised multicell processing
Joint and distributed linear precoding for centralised and decentralised multicell processing
Linear precoding techniques are designed for both joint and distributed Multi-Cell Processing (MCP), where both centralised and decentralised Channel State Information (CSI) exchange scenarios are considered. The outage rate of various linear precoding techniques is investigated in the cell-edge area of a practical three-cell based cooperative scenario under both fully-loaded and lightly-loaded system configurations, when encountering either no tier-one Co-Channel Interference (CCI) or full tier-one CCI. The numerical results demonstrate the superiority of the low-complexity, yet scalable decentralised Distributed Signal-to-Leakage-Noise-Ratio (DSLNR) based linear precoding technique under realistic CSI quantisation and channel-induced feedback error conditions when full tier-one CCI is considered.

Abstract
Linear precoding techniques are designed for both joint and distributed Multi-Cell Processing (MCP), where both centralised and decentralised Channel State Information (CSI) exchange scenarios are considered. The outage rate of various linear precoding techniques is investigated in the cell-edge area of a practical three-cell based cooperative scenario under both fully-loaded and lightly-loaded system configurations, when encountering either no tier-one Co-Channel Interference (CCI) or full tier-one CCI. The numerical results demonstrate the superiority of the low-complexity, yet scalable decentralised Distributed Signal-to-Leakage-Noise-Ratio (DSLNR) based linear precoding technique under realistic CSI quantisation and channel-induced feedback error conditions when full tier-one CCI is considered.
