This paper presents a novel framework for separating and reconstructing multichannel speech sources from compressively sensed linear mixtures simultaneously. The conventional approaches for blind speech separation are almost based on the Nyquist sampling theory. We proposed an approach which uses the multichannel compressive sensing theory for blind speech separation. The linear programming and gradient-based...
One-cycle control technology is used for three-phase high power factor converter, one-cycle control equation is presented, the corresponding control circuit and main circuit are designed, and a simulation study is done. Simulation results shows that the input current of three-phase high power factor converter can track the input voltage very well, a unity power factor correction is achieved, and the...
A model is designed to analyze investment strategy of Chinese sovereign wealth fund (SWFs) based on specific investment objectives and investment fields, regarding SWFs as one part of the whole economy. The research focused on the establish conditions, the optimal scale and the impact on the whole national welfare of China strategic SWFs. The theoretical analysis and simulation suggest that the establishment...
The evaluation system is investigated for the disturbing effect of optical countermeasure device to photoelectrical guided weapon in this paper. The general optical countermeasure simulation model is established by using photoelectrical countermeasure simulation test to conduct the estimation of countermeasure effect. The target-missing quantity of guided weapon and guided precision is designated...
Previous research has shown that the synergy of collaborative herding behavior and market sentiment is one of the internal mechanisms for stock market volatility. In this paper, inter-agent imitation and the simulation of the collaboration of market sentiment signals are conducted on a platform of computational experiments. The results of the experiments show bubbles or collapse of stock price due...
Cooperative spectrum sensing has greatly improved the performance of the cognitive radio. If the cognitive users belong to different groups, they seem to be less insensitive to achieve a higher throughput. In this paper , an evolutionary game framework is proposed to study the interactions between selfish users in the cooperative sensing .We compare the dynamics and the stationary strategy of the...
This paper presents a LED(light emitting diode) backlight driving system for automobile panels. A new scheme is presented and compared to the conventional scheme, and the simulation model for new scheme is presented and used to simulate the system. The study indicates the necessity of a technique for current equalization when using parallel LED arrays system.
