In view of computer technology widespread application in building where all kinds of information convergence, proposing the building numerical information integration, which aims at impelling the level conformity information of building, providing the advantageous support for intelligent building, the ecologically-safe building, and the energy efficiency of building, exploring the new direction of...
In this paper, we present the concept of a PCI-based GPS receiver architecture with the aim of providing a platform for investigating new receiver architectures and algorithms for current and upcoming GNSS receivers. We designed and implemented the RF front end, the baseband signal processing module and the PCI interface circuit, which compose a GNSS receiver. The work of hardware testing was carried...
The short term flicker severity Pst is an important index of power quality in the standards of IEC. Usually Discrete Fourier Transform (DFT) is used to calculate Pst, due to the inherent spectral leakage and barrier effect of DFT lead to low accuracy of Pst, therefore a method to improve the accuracy of Pst is proposed in this paper, the corn of this method is that, using DFT and Discrete Fourier...
Pulse diagnosis is one of the most important examinations in Traditional Chinese Medicine (TCM). In response to the subjectivity and fuzziness of pulse diagnosis in TCM, quantitative systems or methods are needed to modernize pulse diagnosis. In pulse diagnosis, strength is one of the most difficult factors to recognize. To explore the quantitative recognition of pulse strength, a novel method based...
For Wireless Sensor Networks (WSN), target tracking is a canonical problem that collaborates signal and information processing to dynamically manage sensor resources and efficiently process distributed sensor measurements. This paper proposes an adaptive sensor scheduling strategy that jointly sets up distribute dynamic clustering, selects the tasking sensor, and determines the sampling interval....
A synchronous audio watermarking algorithm based on chaotic encryption in DCT domain is presented in the paper, which uses the synchronic signal to locate the watermark. The watermark and the synchronic signal are embedded into the low frequency components by quantization. Experiment results show that the proposed watermarking scheme is imperceptible and robust against various signal processing, such...
According to the present situation that respirable coal mine dust concentration can not be on-line detected real-timely, a real-time respirable coal mine dust concentration acquisition method that use real-timely detected total coal mine dust concentration combined with calculation of conversion coefficient was put forward. The method obtained respirable coal mine dust concentration through detecting...
The contourlet transform [CT] is a new two-dimensional representation for images that can capture the intrinsic geometrical structure of pictorial information. The construction proposed in this paper is based on a nonsubsampled pyramid structure and critically sampled directional filter banks. The proposed transform impartially takes into account the redundancy and the data amounts. Our experiments...
