| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Propagator method is known as a fast DOA estimation algorithm because it does not require eigenvalue decomposition and angle scanning. In this paper, we compared Propagator method with Beamformer, Root-MUSIC and TLS-ESPRIT. The superiority of Propagator method is verified with its accuracy and computational effort. The estimation accuracy is evaluated by using both the experiment result in radio anechoic chamber and simulation result. The computational effort is evaluated by comparing of number of multiplications from received signal to deriving the result of DOA estimation. When the estimation accuracy is almost equal, in both simulation and experiment, the number of multiplications that Propagator method requires is tens of percent for other algorithms. We show that Propagator method is a fast algorithm in the case of desired estimation accuracy. |
