This is a study on the issue of noise robustness of text independent Speaker Identification (SID). Over the past years, SID technology has emerged as extremely important tool with applications in security and authentication. The current technology works well in presence of matched acoustic conditions for training and testing but the performance shows immediate loss in mismatched conditions. Our broad...
The environment of a mobile ad hoc network may vary greatly depending on nodes' mobility, traffic load and resource conditions. In this paper we categorize the environment of an ad hoc network into three main states: an ideal state, wherein the network is relatively stable with sufficient resources; a congested state, wherein some nodes, regions or the network is experiencing congestion; and an energy...
This paper presents a continuous decoding algorithm combined with adaptive equalization for receiving UWB signal in indoor multipath channel. It provides theoretical analysis and simulation results based on multiuser environment. This new algorithm computes initial forward recursion using training sequence needed by the adaptive equalizer, and uses lower constraint length to reduce memory consumption...
The load distribution on the wallboard is the basis of structure optimization of the wallboard of printing press. A testing method of dynamic strain on the wallboard of printing press is presented. By analyzing the arrangement of printing cylinders and transferring mechanism and other main components, the tested point positions with the strain information of the wallboard are determined. A kind of...
A novel method on motion precision for high speed adjustable rotor set is presented, concerning the intangible mechanical precision for a micro coating device. In the equipment to carry out micro material being coated, it is essential for adjustable rotor set to be determined its economic manufacturing precision so as to meet the procedure’s demand. With a component coordinate frame for each roller...
