采用多策略改进Jaya算法的室内三维VLP研究
Research on indoor 3D VLP using the multi-strategy improved Jaya algorithm
摘要
Abstract
An indoor visible light positioning(VLP)scheme based on the multi-strategy improved Jaya algorithm is proposed for the indoor 3D VLP problem of a single light-emitting diode(LED),taking into account the influence of non-line-of-sight(NLOS)links.Specifically,in this indoor 3D VLP system model,the NLOS link is considered as an interference,and the PAM-DMT-based least squares(LS)channel estimation is utilized to estimate the LOS link channel gain,and then the sum of the squares of the difference between the estimated channel gain and the channel gain computed at the test point is used as the fitness function,and the multi-strategy improved Jaya algorithm is used for the search and optimization to realize the localization.Subsequently,the 3D positioning errors of different numbers of PDs at different inclination angles and heights are simulated and compared,and the convergence and performance of the proposed multi-strategy improved Jaya algorithm are compared with those of the other four algorithms.The results show that the LS channel estimation method based on PAM-DMT can effectively reduce the localization error due to NLOS interference,and that the average localization error of the system with channel estimation is reduced by 84.64％compared with that of the system without channel estimation.When the number of PDs in the receiver is 5 and the inclination angle is 75°,the fluctuation of the positioning error with height is the lowest and the average positioning error is the smallest under the consideration of the NLOS link.Compared with the other four algorithms,the multi-strategy improved Jaya algorithm has a higher positioning accuracy as well as fewer iterations.The work in this paper will be of some reference value for the study of the indoor single-LED VLP system.关键词
