Capacity Bounds and Exact Results for the Cognitive Z-interference Channel
Nan Liu, Ivana Maric, Yinghui Cheng +2
We study the discrete memoryless Z-interference channel (ZIC) where the transmitter of the pair that suffers from interference is cognitive. We first provide an upper bound on the…
A unified graphical approach to random coding for multi-terminal networks
Stefano Rini, Andrea Goldsmith
A unified graphical approach to random coding for any memoryless, single-hop, K-user channel with or without common information is defined through two steps. The first step is user…
Reduced-dimension multiuser detection: detectors and performance guarantees
Yao Xie, Yonina C. Eldar, Andrea Goldsmith
We explore several reduced-dimension multiuser detection (RD-MUD) structures that significantly decrease the number of required correlation branches at the receiver front-end, whil…
Downlink Performance and Capacity of Distributed Antenna Systems
Sina Firouzabadi, Andrea Goldsmith
This paper investigates the performance of the downlink channel in distributed antenna systems. We first establish the ergodic capacity of distributed antennas, under different cha…
Reduced-Dimension Multiuser Detection
Yao Xie, Yonina C. Eldar, Andrea Goldsmith
We present a reduced-dimension multiuser detector (RD-MUD) structure for synchronous systems that significantly decreases the number of required correlation branches at the receive…
Shannon Meets Nyquist: Capacity of Sampled Gaussian Channels
Yuxin Chen, Yonina C. Eldar, Andrea J. Goldsmith
We explore two fundamental questions at the intersection of sampling theory and information theory: how channel capacity is affected by sampling below the channel's Nyquist rate, a…
