Most resource allocation algorithms are based on perfect channel and constant system parameters information in cognitive radio networks (CRNs). In order to adapt real communication environment, a dynamic particle swarm optimization (DPSO) power control algorithm based on underlay cognitive radio networks (CRNs) is presented to minimized total transmit power of SUs in consideration of three constraints, namely, interference temperature constraint of PUs, transmit power constraint of each SU, and constraint of minimum SINR at secondary receivers. The comparison of simulation result among DPSO algorithm, particle swarm optimization (PSO) and chaos particle swarm optimization (CPSO) algorithms is provided to show that DPSO can get minimum transmit power of SUs, fast convergence rate, and stability to cognitive radio networks under dynamical environment. ©, 2015, Binary Information Press.

Distributed power control algorithm in multiuser cognitive radio networks for minimizing interference to primary user

引用

Journal of Computational Information Systems 2015年第5期11卷 1799-1808页

In order to guarantee quality of service (QoS) for secondary users (SUs) and primary users (PUs) in underlay cognitive radio networks (CRNs), the objective of this paper is to obtain minimum interference power to PUs under the constraints of the maximum allowable transmission power and the minimum signal to interference plus ratio (SINR) of each SU, which reduces the total interference from SUs to PUs and energy consumption of all SUs. An improved distributed power control algorithm (IDPCA) is proposed on the basis of standard distributed power control algorithm (SDPCA) from convex optimization theory. Simulation results show that the performance of two proposed algorithms are superior to the traditional iterative water filling algorithm (IWFA) in perfect and imperfect channel environment, and the improved algorithm is better than the standard distributed algorithm.

A new method is studied and designed in this paper to strengthen the adaptability and practicability of frequency-hopping (FH) signal detection under the complicated electromagnetic environment. The proposed method includes four processing algorithms: channelization, estimation of the background noise, selection of the FH channel, and FH signal detection. Through this method, FH signals can be effectively detected under the complicated environment even with strong interference. The simulation and results suggest this method improves the accuracy of FH signal detection and signal-to-noise ratio greatly.

The car still represents the bulk of urban transport in large cities. However the weight of the car tends to be reduced as a result of public policies, the emergence of new transport alternatives and the increasing cost of use of private vehicles. Public transport are not enough to resolve the problems of urban mobility and soft modes (walking and cycling) being relevant only for short distances and mild weather conditions. Nowadays, the collaborative models (carpooling and car-sharing) are increasingly popular and appear among the possible solutions. In this paper, we present new extensions of MATSim to support modeling and simulating carpooling and car-sharing trips. The new modules are totally integrated in MATSim and we carried out a validation study of our results with real data collected in the Grater Region.

A new method of high-speed object detection using planar capacitive sensor was presented. The planar capacitive consists of two electrodes. A sine signal was applied on one electrode to form a quasi-electrostatic field and another electrode was use to detect the object signal. The voltage of the detecting electrode is changed when an object approached to the planar capacitive. The detection model of the planar capacitive sensor was established. The relationship between the rendezvous distance and the voltage variation was deduced. The increase of the electrode diameter and the decrease of the electrodes space contributed to the improvement of the capacitive sensor's sensitivity. The experimental results showed that the planar capacitive sensor could achieve short range detection for high-speed object.

In order to solve the key technical problem in the verification process of mechanical and electrical coal mine anemometer, the paper presents digital recognition approach base on the characters of the anemometer image. First of all, collect the mirror images of the anemometer from a plain mirror which in the wind tunnels. And then we process the mirror images with secondary mirroring, grayscaling, denoising and binarization. Followed the location of the digital area can be determined and the incline distortion of the image can be adjusted. The final step is segmenting the single character in the digital character region and identify the corresponding number base on the characteristics of anemometer, which using the LED digital tube to display numbers. The experiments show that this method can accurately identify the numbers on the anemometer and has high recognition rate. The recognition time is able to meet the requirement for the verification of anemometer. Thus the method has high practical value. © 2014 SERSC.

The widespread use of airborne vehicles and its growing applications in various domains can be attributed to their ability to operate in inaccessible areas, thus decreasing the human loss in major accidents, and making access easy to dangerous conditions. These pilotless airborne vehicles with some remote sensing techniques involved in it, are emerging as a new technology. The airborne vehicles are enduring, cost effective and also provide a reliable platform for surveying. Consequently, small airborne vehicles, here Quad copter, equipped with sophisticated components can capture and transmit the image or video to the Data Base. They are sent for processing and made accessible to the Geographical Information System (GIS), where further analysis is done for the proceedings of the rescue operation. This application finds a great utility predominantly in industries and military.

Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum properties, such as entanglement, may exhibit entirely different behavior to purely classical systems. By measuring this effect or lack thereof, we can test the hypotheses behind several such models. For instance, as predicted by Ralph and coworkers [T C Ralph, G J Milburn, and T Downes, Phys. Rev. A, 79(2):22121, 2009;T C Ralph and J Pienaar, New Journal of Physics, 16(8):85008, 2014], a bipartite entangled system could decohere if each particle traversed through a different gravitational field gradient. We propose to study this effect in a ground to space uplink scenario. We extend the above theoretical predictions of Ralph and coworkers and discuss the scientific consequences of detecting/failing to detect the predicted gravitational decoherence. We present a detailed mission design of the European Space Agency's (ESA) Space QUEST (Space - Quantum Entanglement Space Test) mission, and study the feasibility of the mission scheme.

The research method of identification of the electronic equipment's power-on characteristics based on the data of bus voltage ripple is introduced. The main purpose is to achieve the recognition of the equipment's power-on characteristics through a certain algorithm design, and provide reference for the follow-up intelligent applications of the bus-ripple-tester. Two methods are used here. One is frequency spectrum analysis based on the collected signals. Due to the differences of spectrum distribution between these equipment's signals collected before and after their power-on time, the frequency band of each equipment's characteristic distribution is different, which make it possible to achieve the purpose of identification. The other is the time-frequency analysis based on wavelet transform. According to the difference of wavelet energy of the equipment's signals collected before and after their power-on time, the equipment can be recognized.
