Downlink beamforming in clustered cooperative multicell MIMO systems

2012 IEEE International Conference on Communication Systems (ICCS), 2012
Base station cooperation has been shown to be an effective way to increase the system capacity and to suppress interference in mobile communications. A clustered multicell system is studied in this paper, where the mobile stations (MSs) will encounter intra-cluster and inter-cluster interference.

Cooperative beamforming in multihop amplify-and-forward relay networks

2015 IEEE 26th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2015
This paper studies cooperative beamforming in multihop amplify-and-forward relay networks. We adopt a layer-by-layer approach, namely per-layer sum-rate maximization, to compute the beamforming weights employed by the relays at each layer. When there is only one receiving node at the adjacent downstream layer, the per-layer sum-rate maximization ...

Cooperative Multiuser Beamforming in mmWave Distributed Antenna Systems

IEEE Transactions on Vehicular Technology, 2018
In the fifth-generation (5G) system, millimeter-wave (mmWave) communication has been recognized as a candidate technique. To overcome the high transmission loss of mmWave, distributed antenna systems that consist of a base station (BS) connecting with multiple remote radio units (RRUs) were studied to improve the energy efficiency.

Weighted Cross-Layer Cooperative Beamforming for Wireless Networks

IEEE Transactions on Signal Processing, 2009
In wireless networks, implementing cooperative beamforming (CB) can enable long-range communications in an energy efficient manner. By appropriately weighting and forwarding message signals, the cooperating nodes form one or more beams to cooperatively transmit one or more message signals to the desired destinations.

Self-synchronized Cooperative Beamforming in Ad-Hoc Networks

2014
We investigate the unicast problem for ad-hoc networks in the plane using MIMO techniques. In particular, we use the multi-node beamforming gain and present a self-synchronizing algorithm for the necessary carrier phase synchronization. First, we consider n nodes in a grid where the transmission power per node is restricted to reach the neighboring ...

Noncooperative and Cooperative Transmission Schemes with Precoding and Beamforming.

2008
The next generation mobile networks are expected to provide multimedia applications with a high quality of service. On the other hand, interference among multiple base stations (BS) that co-exist in the same location limits the capacity of wireless networks. In conventional wireless networks, the base stations do not cooperate with each other.
