摘要：
The maximum likelihood method is a promising technology for the calculation method of location estimation of the MSs (Mobile Station) in a designed area. Generally it requires a large computation to find a location when using the maximum likelihood calculation in the designated area. This paper proposes Fast Hierarchical Searching Algorithm which reduced the number of calculation. And we clarify validity in a computer simulation. The optimum hierarchical number is derived in a closed form for the rectangular area. Example illustrates that original mesh size of 257x257, the calculation is reduced to 175, which corresponds to 1/377.
