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...
متن کاملRobust Multicell Cooperation in MIMO-OFDMA Networks
In future communication systems, the constraint of resource allocation is a challenging topic. The cell edge users in wireless systems experience low Signal to Interference and Noise Ratio (SINR) due to the high InterCell Interference (ICI) and cannot fully benefit from Multiple-Input Multiple-Output (MIMO) multi-stream transmission capability. In this project, a practical approach to the multi...
متن کاملCochannel 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...
متن کاملHandover Sequences for Interference-Aware Transmission in Multicell MIMO Networks
Providing cell-specific reference signals is a basic requirement for advanced transmission techniques reducing the inter-cell interference in the mobile radio network. In this paper, we introduce so-called handover sequences. They consist of a comb cyclically shifted in the frequency domain to identify the cells. Orthogonal sequences in time domain are used to identify the antennas within a cel...
متن کاملAdaptive limited feedback links for cooperative multi-antenna multicell networks
The overall performance of cooperative networks is quite sensitive to channel state information (CSI) of serving and interfering base stations (BSs) and affected strongly by quality of limited feedback links. In this paper, we propose two adaptive limited feedback strategies for intercell interference cancelation in multi-antenna multicell networks. The first proposed strategy is developed to i...
