Pilot tone aided measurements to extend the bandwidth of radio frequency applications
(Elsevier B.V., 2016)
A technique to extend the effective measurement bandwidth of a non-coherent vector receiver is presented. This bandwidth extension technique relies on the use of a pilot signal (known a priori), which is added on the signal ...
Pattern recognition theory in nonlinear signal processing
(Kluwer Academic Publ, 2002-05-01)
A body of research has developed within the context of nonlinear signal and image processing that deals with the automatic, statistical design of digital window-based filters. Based on pairs of ideal and observed signals, ...
Signaling cascades transmit information downstream and upstream but unlikely simultaneously
(BioMed Central, 2016-08)
Background: Signal transduction is the process through which cells communicate with the external environment, interpret stimuli and respond to them. This mechanism is controlled by signaling cascades, which play the role ...
Design of a micropower signal conditioning circuit for a piezoresistive acceleration sensor
(IEEE, 1998)
The design and test of a micropower signal conditioning circuit for a piezoresistive accelerometer is presented. The circuit is intended for sensing human body motion in rate-adaptive cardiac pacemakers. A strategy is ...
Discrete wavelet transform signal analyzer
(2007-10-01)
This paper addresses the problem of processing biological data, such as cardiac beats in the audio and ultrasonic range, and on calculating wavelet coefficients in real time, with the processor clock running at a frequency ...

Enhancing weak signal transmission through a feedforward network
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
The ability to transmit and amplify weak signals is fundamental to signal processing of artificial devices in engineering. Using a multilayer feedforward network of coupled double-well oscillators as well as Fitzhugh-Nagumo ...
