This paper investigates the coexistence issue between pulsed ultrawideband (UWB) radio devices and the existing narrow band IEEE802.11a systems by using the time-reversal method. In this study, the time reversal is applied to the pulsed UWB system. Based on the statistical path loss model, we ...

Time-reversed equations There are a number of systems that can detect partial discharges, but they aren't very effective in pinpointing where they originate. "With our method, engineers can locate the source of a partial discharge and act quickly to solve the problem," says Hamid Reza Karami,...
Time-reversal method (TRM) is based on principle of reciprocity of sound by propagating of a reversal signal in time series to compensate distortion due to path effect in propagation and to focus the signal at the original source location. In recent years, the technique has been applied in op...

A novel method to solve inverse problems for the wave equation is introduced. The method is a combination of the boundary control method and an iterative time reversal scheme, leading to adaptive imaging of coefficient functions of the wave equation using focusing waves in unknown medium. The appr...
Time of Arrival Data Fusion Method for Two-Dimensional Ultrawideband Breast Cancer Detection A new microwave imaging method is given for breast tumor detection using an ultrawideband (UWB) imaging system. By combining the time of arrival (TOA) meas... Y Chen,E Gunawan,KS Low,... - 《IEEE...
We then extend the source time reversal method, originally developed for acoustic waves, to an elastic system of waves. Additionally, we present a fast reconstruction implementation for large data sets. This is especially useful in the elastic case, in which the numerical cost is higher than in...
This method based on the Feshbach projection formalism provides an alternative to popular methods such as the Feynman diagrammatic techniques and the master equation approach that are commonly used for studying open quantum systems. It is ... A Tayebi 被引量: 0发表: 2017年 UWB patch antenna and...
