Proceedings ArticleDOI
Compressed sensing based UWB receiver: Hardware compressing and FPGA reconstruction
TL;DR: A low sampling rate approach for recovering ultra wide band (UWB) signals is proposed, using Distributed Amplifiers (DAs) and low speed Analog-to-Digital Converters (ADCs), based on the theory of compressed sensing.
Proceedings ArticleDOI
FPGA Implementation of Evolvable Block-based Neural Networks
TL;DR: This paper presents an intrinsic online evolution system that can be genetically evolved and adapted to changes in input data patterns dynamically without any need for multiple FPGA reconfigurations to accommodate various network structure/parameter changes.
Journal ArticleDOI
Beyond execution time: expanding the use of performance models
TL;DR: An analytic model is developed for synchronous iterative algorithms running on distributed-memory MIMD machines, and refined it for disrete-event simulation that describes the execution time of a single run in terms of application parameters such as the number of iterations and the required computation in each.
Journal ArticleDOI
Compressive sensing based sub-mm accuracy UWB positioning systems: A space-time approach
TL;DR: Simulation results show the proposed STBCS algorithm can significantly reduce the number of measurements and has better noise tolerance than the traditional BCS, OMP, and multi-task BCS (MBCS) algorithms.
Proceedings ArticleDOI
Millimeter accuracy UWB positioning system using sequential sub-sampler and time difference estimation algorithm
TL;DR: In this paper, a compact sequential sampling scheme using a high sampling rate analog digital converter (ADC) and direct digital synthesis (DDS) technology has been proposed for the millimeter accuracy UWB positioning system, which can achieve the equivalent of a 100GHz sampling rate.
