The estimation of sparse vectors is an important problem in digital signal processing. Recently, efficient iterative algorithms based on the so-called linearized Bregman iterations have been proposed, combining excellent estimation performance with low implementation complexity. Unfortunately, these algorithms typically use large numerical values, complicating fixed point implementations. To overcome...
The positioning technology is one of the most important technologies in the wireless sensor network. The paper describes the current international positioning on several existing technologies, including the based ranging RSSI, TOA, TDOA, etc. and non-centroid algorithm based on distance, Amorphous algorithm, APIT algorithm and so on. Dv_Hop algorithm is a distributed localization algorithm based on...
The paper presents an algorithm for localization of endoscopic capsules inside the human body. The goal is to determine the position of capsules by measuring the power of received electromagnetic signal on the human skin taking into account losses within the body. The algorithm was first developed and simulated in MATLAB. Simulation results prove its high accuracy and indicate the optimal antenna...
This paper presents an error-resilient wavelet-based ECG processor under voltage overscaling (VOS). A novel predictor based on weighted-average bilateral estimation (WBE) is proposed and used for algorithmic noise tolerance (ANT) that compensates the VOS-incurred errors. A two-stage ANT mechanism using heterogeneous error-detection techniques is developed, which enhances the robustness of ANT. This...
Laboratory assignments for Embedded System courses are usually performed with a hardware-based training kit that equipped with an embedded system board, software development tools, and optionally an emulator for debugging. Using the hardware-based kits has some demerits such as high initial setup cost, burdensome maintenance, lacks of adaptability to industry evolution, and restricted educational...
Power estimation and verification have become important aspects of System-on-Chip (SoC) design flows. However, rapid and effective power modeling and estimation technologies for complex SoC designs are not widely available. As a result, many SoC design teams focus the bulk of their efforts on using detailed low-level models to verify power consumption. While such models can accurately estimate power...
