The goal of this paper is to design and evaluate a new practical algorithm for wireless detection of human respiration rate behind an obstacle using UWB signals. First, a motion phantom is designed for simulating chest cavity motion which the frequency and range of its motion are fully controlled by user. Then, Experiments are carried on the phantom by a 3.2 GHz Ultra Wide-Band (UWB) transceiver....
The purpose of this paper is to introduce an accurate algorithm to detect respiration rate and heart beat using an Ultra-Wideband (UWB) signal. One important issue to consider for obtaining precise results is the right selection of measurement parameters in UWB system. In this work the impact of these parameters in detecting respiration rate and heart beat are studied and the best values are suggested...
UWB signals have become attractive for their particular advantage of having narrow pulse width which makes them suitable for remote sensing of vital signals. In this paper a novel approach to estimate periodic motion rates, using ultra wide band (UWB) signals is proposed. The proposed algorithm which is based on wavelet transform is used as a non-contact tool for measurement of respiration motion...
Ultra-Wide Band (UWB) signals have become attractive for their particular advantage of having narrow pulse width which makes them suitable for remote sensing of vital signals. In this work, a MATLAB framework is presented which simulates an environment whereby the UWB signals can be observed and evaluated at different locations of the simulated channel for wireless measurement of heart rate. Main...
Frequency analysis using the discrete cosine transforms (DCT) is an obvious choice for digital signal and image processing domain. This paper describes the implementation of 2D-DCT processor for the synchronous design in a Xilinx VertexIV FPGA device. The DCT core architecture is based on the distributed arithmetic. The total dynamic power of the processor is 371 mW, in an operating frequency of 118...
