Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, wireless communications are widely used, and researches on DOA (Direction Of Arrival) estimation techniques and evaluation method for the DOA estimation accuracy have been investigated in order to minimize the effects of interferences on wireless communications. Conventionally, DOA estimation accuracy is examined by comparing the direction of the spectrum peak and true direction of the source. However, to obtain the correct DOA estimation accuracy, many trials are required.
In this paper, a simplified evaluation method for DOA estimation accuracy using the spectrum width is proposed. And, effectiveness of proposed method is examined. It is numerically shown that the actual accuracy can be estimated by the proposed method. Moreover, computational resources can be saved because the number of trials of proposed method is decreased compared with conventional method. It is also shown that the error of the proposed method is reduced less than 0.2deg.
