MOBILE TERMINAL LOCATION WITH AN EFFICIENT GEOMETRY-CONSTRAINED BASED ON PSO ALGORITHM IN NLOS ENVHtONMENT
Finding the location of the mobile phone is one of necessary features in 3G/4G communication system. Nonetheless, for many practical applications, location estimation accuracy is not satisfactory due to the unavoidable non-line-of-sight (NLOS) propagation is spread in mobile environment.In order to address this problem, an efficient geometryconstrained based on Particle Swarm Optimization (PSO) algorithm is proposed.The PSO algorithm has high convergence speed and low error for nonlinear calculation in geometry positioning estimation.The simulation results demonstrate that the proposed location scheme can meet the demand of E-911 standard.
