SA antenna-based DOA measurements for LTE base station environments

This report shows that arrival waves of different base stations can be discriminated by a simple DOA (Direction of Arrival) measurement method based on synthetic aperture (SA) antennas that offers high accuracy. Specifically, demodulation and channel estimation for LTE are added to an existing DOA measurement method. An experiment confirms that the angle and level difference of arrival waves for each base station can be accurately determined.
