A location estimetion in 3-D space on Viterbi Algorithm
Takeharu Kohri (SIST) MoMuC2008-82
Abstract (in Japanese) (See Japanese page) 
(in English) I have developed a novel location estimation method that is based on the Viterbi algorithm. Using this method enables us to estimate the most likely location at several 10 nsec by using past location transition and signal detection. In addition, the system implementing this method can be composed of a single LSI.
Since the Viterbi algorithm has two functions, signal detection from noisy received signal and finding a maximum likelihood sequence path, this method can be applied to location estimation. The level of the received signal is proportional to the distance between the move terminal and the fixed node. The trellis of Viterbi decoder encoder is similar to the track of move terminal.
The Viterbi algorithm has no backward search such as Fano algorithm, so the time needed for detection is fixed and short. The scale of the execution circuit is reduced with the truncation path memory because of the survivor path selection.
