Waveforms with low autocorrelation sidelobes are favorable to weak target detection and synthetic aperture radar (SAR) imaging. In this paper, we aim at solving the problem of designing waveforms with low autocorrelation sidelobes at specified intervals. Thus an amplitude optimization method (AOM) is proposed to minimize the weighted integrated sidelobe level (WISL) of the autocorrelation. By regarding...
Spectrum sensing is one of the most important technologies for cognitive radio. In order to decrease the effect of low SNR, and increase the reliability spectrum sensing performance, we propose a novel spectrum sensing approach, which collects the distributed collaborative beamforming signals as the test statistic to input the energy detector. In particular, the collaborative beamforming method can...
The networked manufacturing aims to satisfy customer’s individual demands. It has three-tier architecture: customer server-web server-logic server and it realizes the functions of individual customization and cooperative design. The supply chain based on networked manufacturing is distinguished from the traditional supply chain. It unfolds its operation by the supporting of technique center. Networked...
Collaborative design is new design style to meet the increasing requirement of global market, which share various resources and information of different designers with the aim of reaching the purpose. Designers complete the same task in different places. Designers work at the same time will encounter the conflict, which is a critical problem for collaborative design. Firstly, the class of conflict...
