Although electro larynx speech provides an important means for the laryngectomees for oral communication, the resulting speech is of poor intelligibility due to the radiated noise caused by the instrument. This paper concentrates here on the derivation of a minimum mean-square error spectral amplitude estimator, and on its application in electro larynx speech enhancement, also, the frequency domain...
The Gaussian mixture probability hypothesis density (GM-PHD) filter method is presented, which is a closed-form solution to the probability hypothesis density (PHD) recursion. The approach involves applying the Kaiman filter to predict and update the probability hypothesis density (PHD), which is a first order statistic of the random finite set of targets. The GM-PHD not only has a good tracking performance,...
In this paper, a 1-V 8-bit 10 kS/s successive approximation (SA) analog-to-digital converter (ADC) with ultra-low power characteristic is implemented for biosignal acquisition systems. To decrease power consumption, a passive sample-and-hold (SH) circuit and an opamp-free, capacitor-based digital-to-analog converter (DAC) are utilized. The only active circuit, a comparator, is implemented in the sub-threshold...
