The security of the information is very important for wireless communication system, and chaotic radio modulation can provide new protection for the information. A bandpass chaotic signal design method is introduced to restrain the DC and the spectrum components in the low frequency of the chaotic signal which can be used as the radio carrier for the chaotic modulation. The N + 1 dimensions system...
Due to the enormous amount of DNA sequences to be processed, the computational speed is an important issue to be considered. Although relatively high accuracy has been achieved by existing methods, most of these prediction methods are computationally intensive. In this paper, a novel method for predicting DNA splice sites using improved bayesian classifier is presented. Naive bayesian classifier is...
With the exponential growth of genomic sequences, there is an increasing demand to accurately identify protein coding regions from genomic sequences. Despite many progresses being made in the identification of protein coding regions by computational methods during recent years, the performances and efficiencies of the prediction methods still need to be improved. A novel method to predict the position...
Inductor is a very popular device in various circuits. A PCB (printed circuit board) inductor makes its size more compact. When the signal frequency reaches to radio or microwave bands the radiation and scattering from it must be considered. Electromagnetic scattering from a PCB inductor is studied in this paper. Combining Mom with wavelet analysis sparsifies the matrix produced in calculation, which...
This paper presents a kind of enhanced DCSK method. It belongs to chaotic on-off communication, which has developed from the initial form COOK (chaotic on-off keying) and CSK (chaos shift keying) to the more superior one- DCSK, a kind of communication way of most practical value at present. Simulation results show that the BER is better than that in the former DCSK system under the condition of the...
