Abstract :
Nowadays, positioning favored to have the best accuracy to estimate position standing on the basis of time among all of estimation techniques. ToA estimation and TDoA estimation are typical techniques based on time. ToA is known that it is more accurate than TDoA but calculating time of ToA burden. Moreover, the calculating time increases with the increase of reference nodes. In this paper, we propose the ToA position estimation technique using MHP pulse to reduce the calculating time. We compare the proposed ToA estimation with conventional ToA and conventional TDoA, and make a simulation result the reduced calculating time of proposed ToA.
