Signal Processing for Communications

With a novel, less classical approach to the subject, the authors have written a book with the conviction that signal processing should be taught to be fun. The threatment is therefore less focused on the mathematics and more on the conceptual aspects, the ...

Dataflow/Actor-Oriented language for the design of complex signal processing systems

Marco Mattavelli, Christophe Lucarz, Ghislain Roquier

Signal processing algorithms become more and more complex and the algorithm architecture adaptation and design processes cannot any longer rely only on the intuition of the designers to build efficient systems. Specific tools and methods are needed to cope ...

How to Make Stream Processing More Mainstream

Marco Mattavelli

Stream processing has a long history as a way of describing and implementing speciﬁc kinds of computational processes. So far, however, it has largely remained an exotic ﬁeld of endeavor, with relatively small momentum compared to traditional von Neumann c ...

Multicast Parametric Synchronous Sampling

Camille Sophie Brès

A new technique for real-time processing of arbitrary optical signals is proposed and experimentally demonstrated. A parametric processor was used to form multiple signal copies, synchronize intercopy delays, and perform simultaneous sampling of spectrally ...

Parametric joint-coding of audio sources

Christof Faller

The following coding scenario is addressed: A number of audio source signals need to be transmitted or stored for the purpose of mixing wave field synthesis, multi channel surround, or stereo signals after decoding the source signals. The proposed techniqu ...

Oversampled A/D Conversion and Error-Rate Dependence of Non-Bandlimited Signals with Finite Rate of Innovation

Ivana Jovanovic

We study the problem of A/D conversion and error-rate dependence of a class of non-bandlimited signals which have a finite rate of innovation, particularly, a continuous periodic stream of Diracs, characterized by a finite set of time positions and weights ...

Digital adaptive phase noise reduction in coherent optical links

Ali H. Sayed

Coherent optical links enable high-density constellations and, consequently, a higher throughput. However, the phase noise associated with the transmitter and the receiver lasers is a challenging issue in coherent lightwave systems. The authors present an ...
