| Abstract(in English) | This paper proposed a new method of direction of arrival (DOA) estimation, which can be used in high speed tracking systems for the mobile wireless communications using the OFDM. The MUSIC estimates the DOA of all arriving signals, but can't specify the DOA of the target signal. The proposed method specifies the DOA of the target signal using the correlation between the signals received in the start symbol periods that are repeated in the preamble of the OFDM packet. Then non-target signals are suppressed, and the target signal remains in the correlation matrix of the signals received by each elements of the array. Using this correlation matrix in MUSIC, the DOA of the target signal can be estimated. The proposed method is evaluated in the condition of the 4 elements array antenna, and the average gain is improved to be more than 9dB(max) of the conventional tracking method. |
