Abstract
Current indoor location fingerprint positioning system is mainly used to the mobile terminal posi-tioning. Based on above system's mechanism,this paper studies the positioning of radio transmitter,which belongs to location fingerprint positioning system on platform side. In order to reduce the positioning error through arranging the receivers' positions,a scheme of determining the receivers' positions is proposed with increasing the Euclidean distance between neighboring reference points. At the same time,the number of the receivers is set by the coverage in area of positioning to meet the demand of location. Then the mathe-matical model about the position and number optimization problem of the receiver is established. Genetic algorithm and full coverage principle are used to solve the optimization problem,and the realization process of the optimization problem is given. Simulation researches are carried out for different space to compare the positioning errors between the experience placement of the receiver and optimal placement of the re-ceiver as well as whether the receiver is satisfied with the full coverage. The simulation results show that the proposed method is reasonable. And this method provides some guidance for deploying the number and location of receivers before positioning.关键词
