Cooperative Downlink Multicell Preprocessing Relying on Reduced-Rate Back-Haul Data Exchange

Cooperative MIMO multicell networks

Recently, the pressing desire to provide cost-effective solutions aimed at supporting high-throughput broadband wireless access with large-scale coverage has significantly changed the notion of the traditional cellular systems. Physical layer cooperation serves as an enabling technology for such a change. In latest cellular networks, neighboring infrastructure stations, such as base stations (B...

Downlink Multicell Processing with Limited-Backhaul Capacity

Multicell processing in the form of joint encoding for the downlink of a cellular system is studied under the assumption that the base stations (BSs) are connected to a central processor (CP) via finitecapacity links (finite-capacity backhaul). To obtain analytical insight into the impact of finite-capacity backhaul on the downlink throughput, the investigation focuses on a simple linear cellul...

Multicell Downlink Capacity with Coordinated Processing

This paper considers the application of cooperative base-station (BS) transmission schemes to the downlink of multicell networks. Based on a simplified Wyner-type network model with users clustered at the cell-edges, closed form sum rate expressions for non-fading channels are derived for dirty-paper coding (DPC), linear zero-forcing (ZF) precoding, and co-phasing with reuse. By extending the m...

Cochannel Interference Mitigation and Cooperative Processing in Downlink Multicell Multiuser MIMO Networks

Recently, the remarkable capacity potential of multiple-input multiple-output (MIMO) wireless communication systems was unveiled. The predicted enormous capacity gain of MIMO is nonetheless significantly limited by cochannel interference (CCI) in realistic cellular environments. The previously proposed advanced receiver technique improves the system performance at the cost of increased receiver...
