Abstract

In inverse-GPS (Global Positioning System), intersymbol interference greatly influences the positioning error. The paper deals with a new interference canceller by means of which the error is reduced. The interference canceller which we propose is composed of a DLL (delay locked loop) and adaptive filter. Only a primary phase of a replica signal is estimated in DLL. Then, the exact wave is generated with the adaptive filter. The intersymbol interference error, which is caused and increased by the number of users, is decreased by the interference canceller which is the combined DLL and adaptive filter.
