A reconfigurable wireless health monitoring system with Undecimated Wavelet Transform implemented

摘要

This paper presents a novel wireless health monitoring system based on an embedded reconfigurable platform with CPU and FPGA integrated on a single board. Physiological signals and parameters are acquired by BLE (Bluetooth Low Energy) sensor nodes and transferred to the platform via a BLE dongle connected through RS-232 interface. A UWT (Undecimated Wavelet Transform) core is implemented in the built-in FPGA chip to accelerate signal analysis. The test result shows that this FPGA core runs much faster than the CPU-based UWT function implemented in LabVIEW Real-Time module.
