Based on the homomorphism of Lee et al, Xiang Guangli et al proposed similar module and implemented encrypting operations of addition, subtraction, multiplication and division over real number domain. There was additive and multiplicative homomorphism heretofore. But their cipher text leaks the information of decimal fraction, sign and relationship of big and small. We propose additive, subtractive,...
This paper studies the effect on the change of industry structure brought by enterprises' growth in mobile internet industry. Based on the horizontal and vertical integration model, it establishes the multi-agent stimulation model of the evolution of mobile internet with Netlogo. In this model, internal-growth is depended on the financial affair, technology, management skill, human capital, innovation...
This paper studies the mobile tracking problem in mixed line-of-sight (LOS) and non-line-of-sight (NLOS) conditions, where the statistics of NLOS error is Gaussian with fixed but unknown mean and variance. A Rao-Blackwellized particle filtering and parameter learning method (RBPF-PL) is proposed, in which the particle filtering with optimal trial distribution is first applied to estimate the posterior...
An improved Rao-Blackwellized particle filtering (RBPF) is proposed track the mobility of mobile station (MS) in mixed line-of-sight (LOS) or non-line-of-sight (NLOS) conditions in cellular network. The algorithm first estimates the sight condition state using particle filtering method, in which particles are sampled by the optimal trial distribution and selected by one-step backward prediction. Then,...
