Abstract :
A virtual multipath (VM) based technique focusing on mitigating both weak and strong short-delay multipath (MP) signals in the global positioning system (GPS) is presented in this letter. Simulations based on the real GPS signal indicate that the proposed technique is able to achieve an absolute range error within 2 m for multipath-to-direct (M/D) ratio of 0.5 and 6.5 m for M/D of 10.
