Angle of Arrival Characteristics at 20 GHz band in LOS Urban Area Street Cell Environment

In this paper, the SAGE algorithm is applied to measured data acquired by the 20 GHz band channel sounder in a real urban street cell environment, and DOA (Direction of Arrival) is estimated. Then, the average arrival angles and angle spreads are calculated from the estimated results, and angle of arrival characteristics are evaluated. It is shown that the average angle of arrival gradually approaches to direction of transmitter as the distance between the transmitter and the receiver increases. Also, it is shown that the arrival angle spread in the azimuth plane tends to decrease as the distance between transmitter and receiver increases.
