In this report, we try to partially modify the algorithm of particle filter to reduce its computational cost, and then apply it to estimate Direction-Of-Arrival (DOA) and to track mobile communication terminals.
In estimating DOA of moving terminals, we can use only a small number of snapshots because we cannot use old data of which DOA is different with the current DOA. It leads bad estimate accurately, as it is well-known that the estimation accuracy becomes worse when we employ MUSIC method with small number of snapshots.
Therefore we need an algorithm which can accurately estimate DOAs of moving terminals with less number of snapshots.
Here we focus on the algorithm of particle filter which is able to estimate a state of moving objects when you cannot know it directly.
We first modify the algorithm of particle filter to reduce its computational cost, and then apply it to estimate DOAs and to track mobile communication terminals. We discuss the estimation accuracy in comparison with the other algorithms. |
