According to the decline of recognition rate of speech recognition system in the noise environments, an improved perceptually non-uniform spectral compression feature extraction algorithm is put forward in this paper. This method can realize an effective compression of the speech signals and make the training and recognition environments more matching, so the recognition rate can be improved in the...
To fully exploit the performance benefits of relay station (RS), in the two-hop cellular networks covering hotspots, when the number of RSs is predetermined, both RS deployment and frequency reuse scheme are jointly optimized for the purpose of maximizing the system capacity based on the constraints of system demand of capacity and the maximum number of outage demand nodes (MNDN). Further, considering...
This paper proposes a novel method to filter web pages using parsing tree. Firstly, this paper explains how features of noises in web pages can be analyzed and extracted. Secondly, this paper explains how the parsing tree of the web pages can be built using document object model (DOM). Finally, this paper explains how domain specific extraction rules and statistic methods can be deployed to eliminate...
