Abstract:

A parallel interference cancellation based mobile localization algorithm was proposed to mitigate the multiple access interference and to improve the location accuracy in mobile positioning systems. The proposed algorithm will mitigate the near-far effect and the multiple access interference of positioning signals from different base stations by iterative estimating and parallel interference cancellation. Simulation results show that the proposed algorithm will improve the accuracy of mobile localization.

Key words: mobile localization, multiple access interference, parallel interference cancellation
