MODIS has wide spectral range and spatial coverage, as well as the continuous coverage MODIS will provide over time, and observes the Earth as a unified nature, which is necessary for multidisciplinary studies of land, ocean, atmospheric processes and so on, at the same time, it provide us the global data for at least 15 years. All of these characters made the great use of MODIS data. Today the data...
With the rapid development of urbanization, urban construction, every aspect of a great development. Urban housing has also been greatly improved, while the living environment have become increasingly demanding. Concentration in urban traffic caused by an increase in traffic safety, air pollution and noise pollution, etc., all affect the urban living environment. This paper studies the urban road...
This paper proposes a new pitch detection method with the combination of morphology filter and wavelet transform. Before detection, a pre-process based on morphology filter is performed to remove the noise. Then the pitch is detected by wavelet transform. Experiments show that this method can realize pitch period calculation accurately and has a better robustness.
A new adaptive infinite impulse response (IIR) filter structure is proposed based on the input balanced realization. It is generated by the four-multiplier lattice structure. Consequently the controllability Grammian matrix becomes an identity matrix and the algorithm inherently guarantees that the adaptive filter will always remain stable. The simulation result shows that this new adaptive IIR filter...
Several methods are studied in order to improve the communication reliability. However, little methods are discussed aim at medium-voltage power line communication (MV-PLC). In this paper, the general idea of the noise elimination based on single-phase line has been changed. There is a new idea to use three-phase line for noise offset. By analysis of the noise correlation properties, the LMS adaptive...
