Adaptive Rate Sampling and Filtering Based on Level Crossing Sampling
The recent sophistications in areas of mobile systems and sensor networks demand more and more processing resources. In order to maintain the system autonomy, energy saving is becoming one of the most difficult industrial challenges, in mobile computing. Most of efforts to achieve this goal are focused on improving the embedded systems design and the battery technology, but very few studies tar...
متن کاملAn Improved Quality Adaptive Rate Filtering Technique Based on the Level Crossing Sampling
Mostly the systems are dealing with time varying signals. The Power efficiency can be achieved by adapting the system activity according to the input signal variations. In this context an adaptive rate filtering technique, based on the level crossing sampling is devised. It adapts the sampling frequency and the filter order by following the input signal local variations. Thus, it correlates the...
متن کاملAdaptive Rate Sampling and Filtering for Low Power Embedded Systems
This work is part of a large project aimed to enhance the signal processing chain required in embedded systems. The motivation is to reduce their size, cost, power consumption, processing noise and electromagnetic emission. This can be done by smartly reorganizing their associated signal processing theory and architecture. The idea is to combine the signal event driven processing with asynchron...
متن کاملApplication of adaptive sampling in fishery part 1: Adaptive cluster sampling and its strip designs
Abstract: The precision of conventional sampling designs is not usually satisfactory for estimating parameters of clump and rare populations. Many of fish species live in school and disperse all over a vast area like a sea so that they are rare compare to their habitats. Theory of a class of sampling designs called adaptive sampling designs has rapidly grown during last decade which solv...
