Abstract


This paper mainly studies the problem of handheld terminals by using the base station for 3D positioning. Firstly, analyzing the positive correlation between the measured distance and the actual distance from the base station to the handheld terminal by using the algorithm of particle swarm optimization. Then using the least square method to solve the position coordinates of the terminal and determining the terminal position that at least 5 base stations are needed to complete the precise positioning. Afterwards, the motion trajectory of the handheld terminal is obtained by the method of the nonlinear optimization. And the number of base stations that can most effectively locate the terminal is deduced. Finally, the positive correlation function between the degree of connection, the number of base stations and the communication radius is analyzed.

The model used in this paper has the characteristics of low complexity and high accuracy, which lays a theoretical foundation for the research on the posterior aspect of the communication positioning.
