An optimization algorithm of independent mean and variance parameter tying structures for HMM-based speech synthesis
This paper proposes a technique for constructing independent parameter tying structures of mean and variance in HMMbased speech synthesis. Conventionally, mean and variance parame...

Analysis of non-coherent code tracking for NPSK systems in presence of noise and fading
Given the recent interest in non-binary forms of spreading sequences, there is a gap in knowledge on code tracking techniques for noise-like spreading codes. This paper presents t...

Proportionate-type normalized least mean square algorithm with gain allocation motivated by minimization of mean-square-weight d
In previous work, a water-filling algorithm was proposed which sought to minimize the mean square error (MSE) at any given time by optimally choosing the gains (i.e. step-sizes) ...

Online speech source separation based on maximum likelihood of local Gaussian modeling
We propose an online speech source separation method which can separate sources under underdetemined conditions. The proposed method is based on local Gaussian modeling (LGM). At ...
