Multicell Downlink Capacity with Coordinated Processing

We study the potential benefits of base-station (BS) cooperation for downlink transmission in multicell networks. Based on a modified Wyner-type model with users clustered at the cell-edges, we analyze the dir...

Multiaccess Channels with State Known to Some Encoders and Independent Messages

We consider a state-dependent multiaccess channel (MAC) with state noncausally known to some encoders. For simplicity of exposition, we focus on a two-encoder model in which one of the encoders has noncausal acce...

Scalable Ad Hoc Networks for Arbitrary-Cast: Practical Broadcast-Relay Transmission Strategy Leveraging Physical-Layer Network Coding

The capacity of wireless ad hoc networks is constrained by the interference of concurrent transmissions among nodes. Instead of only trying to avoid the interference, physical-layer network coding (PNC) is a n...

A Unified Approach to List-Based Multiuser Detection in Overloaded Receivers

A wireless communication system is overloaded when the number of transmitted signals exceeds the number of receive antennas. The presence of the resulting cochannel interference (CCI) under overload causes lin...
