A simple idea to separate convolutive mixtures in an undetermined scenario
We consider a blind separation problem for undetermined mixtures of two BPSK signals in a multi-path fading channel. We use independence and frequency diversity of the two source s...

Effect of fast AGC on cochlear implant speech intelligibility
This study investigated the effect of fast-acting Automatic Gain Control (AGC) on the speech intelligibility of cochlear implant users as a function of presentation level. Both lo...

Multicode ultra-wideband scheme using chirp waveforms
We propose an ultra-wideband (UWB) scheme that employs chirp waveforms. Signals satisfying the Federal Communications Commission (FCC) requirements for UWB applications are formed ...

Ultrasonic Refractive Index Tomography
Ultrasonic computed tomography (UCT) is one of the methods capable of tissue characterization. It is expected to provide not only a quantitative image but also diagnostic informat...

Direction-resolved estimation of multipath parameters for UWB channels: A partially collapsed Gibbs sampler method
We propose a Monte Carlo method for determining the parameters of multipath components (MPCs) for ultra-wideband channels. A partially collapsed Gibbs sampler is used for jointly ...
