— In this paper, Cramer-Rao lower bounds (CRLBs) for estimation of vital signal parameters, such as respiration and heart-beat rates, using ultra-wideband (UWB) pulses are derive...
A method is described for estimating the fundamental frequencies of several concurrent sounds in polyphonic music and multiple-speaker speech signals. The method consists of a comp...
The complexity of todays hardware systems steadily increases. Due to this fact new ways of efficiently describing systems are investigated. A very promising approach in this area...
Classical sampling records the signal level at pre-determined time instances, usually uniformly spaced. An alternative implicit sampling model is to record the timing of pre-deter...
A faster and more accurate method for the detection of corneal thickness using an ultrasonic pulse-echo technique was proposed. The corneal thickness was calculated from the time ...
