Stochastic Models and Techniques for Sparse Signals

Real-world data such as multimedia, biomedical, and telecommunication signals are formed of specific structures. However, these structures only determine some general properties of the data while the unknown or unpredictable parts are assumed to be random. ...

Concurrent recordings of bladder afferents from multiple nerves using a microfabricated PDMS microchannel electrode array

Stéphanie Lacour, Ivan Rusev Minev

In this paper we present a compliant neural interface designed to record bladder afferent activity. We developed the implant's microfabrication process using multiple layers of silicone rubber and thin metal so that a gold microelectrode array is embedded ...

Approximate Ergodic Capacity of a Class of Fading 2-user 2-hop Networks

Michael Christoph Gastpar, Chien-Yi Wang

We consider a fading AWGN 2-user 2-hop network in which the channel coefficients are independently and identically distributed (i.i.d.) drawn from a continuous distribution and vary over time. For a broad class of channel distributions, we characterize the ...

Decentralized Resource Assignment in Cognitive Networks Based on Swarming Mechanisms Over Random Graphs

Ali H. Sayed

This paper proposes a distributed resource assignment strategy for cognitive networks mimicking a swarm foraging mechanism, assuming that the communication among the cognitive nodes is impaired by random link failures and quantization noise. Using results ...

Optimizing Quantize-Map-and-Forward Relaying for Gaussian Diamond Networks

Christina Fragouli, Ayan Sengupta, I-Hsiang Wang

We evaluate the information-theoretic achievable rates of Quantize-Map-and-Forward (QMF) relaying schemes over Gaussian N-relay diamond networks. Focusing on vector Gaussian quantization at the relays, our goal is to understand how close to the cutset uppe ...

Fluid and white matter suppression with the MP2RAGE sequence

Tobias Kober, José Pedro Rebelo Ferreira Marques, Giulio Gambarota

Purpose: To develop a magnetic resonance imaging (MRI) sequence (fluid and white matter suppression, FLAWS) for generating two sets of images from a single acquisition: one with contrast similar to a T1-weighted magnetization-prepared rapid gradient-echo s ...

A novel low complexity data demodulation algorithm for pulse position modulation

Pierre-André Farine, Cyril Botteron

In this paper, a low complexity data demodulation algorithm is proposed that requires time of arrival information of the received signal exclusively. As an application example, the algorithm is applied to an ultra-wideband impulse radio communication syste ...

Ergodic Interference Alignment

Michael Christoph Gastpar

This paper develops a new communication strategy, ergodic interference alignment, for the K-user interference channel with time-varying fading. At any particular time, each receiver will see a superposition of the transmitted signals plus noise. The standa ...

A novel high-throughput on-wafer electromechanical sensitivity characterization system for piezoresistive cantilevers

Luis Guillermo Villanueva Torrijo

In this work we present the development of a new set-up that allows on-wafer sensitivity characterization of piezoresistive cantilevers. In this way we reduce considerably the testing time compared to the techniques available up to date but at the same tim ...
