Adaptive Hybrid Beamforming with Massive Phased Arrays in Macro-Cellular Networks
Shahram Shahsavari, S. Amir Hosseini, Chris Ng +1
Hybrid beamforming via large antenna arrays has shown a great potential for increasing data rate in cellular networks by delivering multiple data streams simultaneously. In this pa…
Linear Precoding in Cooperative MIMO Cellular Networks with Limited Coordination Clusters
Chris T. K. Ng, Howard Huang
In a cooperative multiple-antenna downlink cellular network, maximization of a concave function of user rates is considered. A new linear precoding technique called soft interferen…
Transmit Signal and Bandwidth Optimization in Multiple-Antenna Relay Channels
Chris T. K. Ng, Gerard J. Foschini
Transmit signal and bandwidth optimization is considered in multiple-antenna relay channels. Assuming all terminals have channel state information, the cut-set capacity upper bound…
Efficient Linear Precoding in Downlink Cooperative Cellular Networks with Soft Interference Nulling
Chris T. K. Ng, Howard Huang
A simple line network model is proposed to study the downlink cellular network. Without base station cooperation, the system is interference-limited. The interference limitation is…
Minimum Expected Distortion in Gaussian Source Coding with Fading Side Information
Chris T. K. Ng, Chao Tian, Andrea J. Goldsmith +1
An encoder, subject to a rate constraint, wishes to describe a Gaussian source under squared error distortion. The decoder, besides receiving the encoder's description, also observ…
Completion Time Minimization and Robust Power Control in Wireless Packet Networks
Chris T. K. Ng, Muriel Medard, Asuman Ozdaglar
A wireless packet network is considered in which each user transmits a stream of packets to its destination. The transmit power of each user interferes with the transmission of all…
