In wireless portable applications, a large part of the signal processing is performed in the digital domain. Digital circuits show many advantages. The power consumption and fabrication costs are low even for high levels of complexity. A well established a ...
The paper presents a programmable triangular neighborhood function for application in low power transistor level implemented Kohonen self-organized maps (SOMs). Detailed simulations carried out for the software model of such network show that the triangula ...
We describe a fully reconfigurable low-density parity check (LDPC) decoder for quasi-cyclic (QC) codes. The proposed hardware architecture is able to decode virtually any QC-LDPC code that fits into the allocated memories while achieving high decoding thro ...

Integrated receiving circuit for radiofrequency signals comprising: an amplifying element (2) using the multiplication zone (5) of a reverse biased semiconductor junction (3, 4) operating in Geiger mode for amplifying an input radiofrequency signal (Vin) a ...
We consider a wireless network with distributed processing capabilities for estimation or detection applications. Due to limited communication resources, the network selects only a subset of sensor measurements for estimation or detection as long as the re ...
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 ...
In this paper we present current mode, programmable, binary tree MIN/MAX filters designed for nonlinear data processing. Proposed circuits can be used in image filtration, to realize operations such as erosion or dilatation that are useful in noise reducti ...
The study of individual cells and cellular networks can greatly benefit from the capabilities of microfabricated devices for the stimulation and the recording of electrical cellular events. In this contribution, we describe the development of a device, whi ...
Multimodal signal processing is an important new field that processes signals from a variety of modalities - speech, vision, language, text- derived from one source, which aids human-computer and human-human interaction. The overarching theme of this book ...
An active implantable chemico-rheological sensor including control electronics, a Digital Signal Processor (DSP) and an RF transceiver has been demonstrated. The ultra-low power system architecture achieves an energy per viscosity measurement of only 16.6m ...
