There are some problems when adaptive arrays are applied to mobile terminals because they utilize several antenna elements on minute terminals. An analysis and evaluation of the effect of antenna element characteristics on SINR of the adaptive arrays is presented in this paper. It is shown that the influence of elements characteristics on the SINR depend on correlation between arrival waves. And it...
This paper addresses a speech recognition problem in non-stationary noise environments: the estimation of noise sequences. To solve this problem, we present a particle filter-based sequential noise estimation method for front-end processing of speech recognition in noise. In the proposed method, a noise sequence is estimated in three stages: a sequential importance sampling step, a residual resampling...
