Subband Beamforming in Coherent Hybrid Massive MIMO Using Eigenbeams
Chris Ng, Mihai Banu
Hybrid Massive MIMO reduces implementation complexity but only supports beamforming coefficients that are common across all subbands. However, in macro cellular where the channel h…
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…
Joint Coding and Scheduling Optimization in Wireless Systems with Varying Delay Sensitivities
Weifei Zeng, Chris T. K. Ng, Muriel Medard
Throughput and per-packet delay can present strong trade-offs that are important in the cases of delay sensitive applications.We investigate such trade-offs using a random linear n…
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…
