Sufficient-Statistics Based Multiple Access over Wireless Fading Channels

Michael Christoph Gastpar

In this work, we study a communication scheme in which nodes transmit sufficient statistics of their observations over non-orthogonal medium access channels for distributed estimation. This scheme unifies and generalizes several multiple access schemes suc ...

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 ...

An Application-Specific Design Methodology for On-chip Crossbar Generation

Giovanni De Micheli, Luca Benini, Srinivasan Murali

Designing a power-efficient interconnection architec- ture for MultiProcessor Systems-on-Chips (MPSoCs) satisfying the application performance constraints is a nontrivial task. In order to meet the tight time-to-market constraints and to effec- tively hand ...

FFT processor for OFDM channel estimation

Andreas Peter Burg

Pilot-assisted channel estimation for communication systems employing orthogonal frequency division multiplexing modulation requires significant signal processing at the receiver if the correlation among the frequency-domain channel coefficients is to be e ...

Sensing reality and communicating bits: A dangerous liaison

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

The successful design of sensor network architectures depends crucially on the structure of the sampling, observation, and communication processes. One of the most fundamental questions concerns the sufficiency of discrete approximations in time, space, an ...
