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…
Distortion Minimization in Gaussian Layered Broadcast Coding with Successive Refinement
Chris T. K. Ng, Deniz Gunduz, Andrea Goldsmith +1
A transmitter without channel state information (CSI) wishes to send a delay-limited Gaussian source over a slowly fading channel. The source is coded in superimposed layers, with…
Minimum Expected Distortion in Gaussian Layered Broadcast Coding with Successive Refinement
Chris T. K. Ng, Deniz Gunduz, Andrea J. Goldsmith +1
A transmitter without channel state information (CSI) wishes to send a delay-limited Gaussian source over a slowly fading channel. The source is coded in superimposed layers, with…
The Impact of CSI and Power Allocation on Relay Channel Capacity and Cooperation Strategies
Chris T. K. Ng, Andrea J. Goldsmith
Capacity gains from transmitter and receiver cooperation are compared in a relay network where the cooperating nodes are close together. Under quasi-static phase fading, when all n…
Capacity Gain from Transmitter and Receiver Cooperation
Chris T. K. Ng, Andrea J. Goldsmith
Capacity gain from transmitter and receiver cooperation are compared in a relay network where the cooperating nodes are close together. When all nodes have equal average transmit p…
