Intelligent Sensors In Software: The Use Of Parametric Models For Phase Noise Analysis

Abstract

Intelligent senors have attracted particular attention in the recent past. This paper argues that an "intelligent sensor" should be able to perform on-board signal processing within the sensor's software in order to produce the optimal signal output. A generic intelligent sensor software architecture is described which builds upon the basic requirements of related industry standards. In this framework, advanced signal processing analyses and algorithms need to be employed. As a case study, we present a novel approach for the analysis of the effect of phase noise in devices such as chemical SAW sensors, gyroscopes, biochemical acoustic wave resonator based sensors and accelerometers.
