| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently, with the spreading of wireless communication technology, importance of a precise direction of arrival (DOA) estimation technology becomes larger in order to investigate propagation environments or determine terminal's positions. An array antenna is used in general DOA estimation algorithms. In a case where antenna element positions of the array are fixed, the higher frequency signal is used, the higher resolution DOA estimation is obtained. However, calculation load increases because we must calculate MUSIC spectra with a narrow angle step. Also, grating lobes occur when using high frequency signals for a fixed element interval. The authors have proposed the DOA estimation method based on the MUSIC algorithm using wide-band signals to solve these problems. First, coarse DOA is estimated at the lowest frequency band where grating lobes do not appear. Next, precise DOA estimation is done at a higher frequency band in a narrower search range to prevent grating lobes and increase of calculation load. In this paper, to estimate DOA using higher frequency signals while avoiding grating lobes, we optimize the frequency, search range, step width. | |
