Delay and coding in multiple-user communications

Stéphane Musy

In multiple-user communications, the bursty nature of the packet arrival times cannot be divorced from the analysis of the transmission process. However, in traditional information theory the random arrival times are smoothed out by appropriated source cod ...

Computation over Multiple-access Channels

Michael Christoph Gastpar

The problem of reliably reconstructing a function of sources over a multiple-access channel (MAC) is considered. It is shown that there is no source-channel separation theorem even when the individual sources are independent. Joint source-channel strategie ...

Non-cooperative Multi-radio Channel Allocation in Wireless Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Mario Cagalj, Shirin Saeedi Bidokhti

Channel allocation was extensively studied in the framework of cellular networks. But the emergence of new system concepts, such as cognitive radio systems, has brought this topic into the focus of research again. In this paper, we study in detail the prob ...

On capacity under receive and spatial spectrum-sharing constraints

Michael Christoph Gastpar

Capacity is often studied under constraints on the channel input signals. This paper investigates the behavior of capacity when constraints are placed on the! channel output signal (as well as generalizations thereof). While such a change in perspective le ...

On the Capacity of a Code Division Multiple Access System

Nicolas Macris, Satish Babu Korada

We consider multiuser communication on a binary input additive white Gaussian noise channel using Randomly Spread-Code Division Multiple Access. We show concentration of various quantities of the system including the capacity and the free energy. We also o ...

Novel Multicode-Processing Platform for Wavelength-Hopping Time-Spreading Optical CDMA: A Path to Device Miniaturization and Enhanced Network Functionality

Camille Sophie Brès

Cost-effective, robust, code-processing photonic devices are essential for the adoption of optical code-division multiple access in future commercial and military network applications. Progress in several technology platforms for code processing is summari ...

Bounds on the capacity region of a class of interference channels

Emre Telatar

We prove a new outer bound to the capacity region of a certain class of interference channels, and quantify the gap between it and the Han-Kobayashi inner bound. The new bound allows the recovery of the El Gamal-Costa characterization of the capacity regio ...

Bits through ARQs: Spectrum sharing with a primary packet system

Michael Christoph Gastpar

We study a problem motivated by cognitive radio in which the primary is a packet system that employs ARQ feedback. A secondary system is allowed to transmit in the same frequency band provided it ensures that the primary attains a specified target rate. Th ...
