摘要： Disclosed is an apparatus and method for estimating a direction of arrival (DOA) of a signal, which improves DOA estimation performance of a reception signal having a low signal to interference and noise ratio (SINR) in a communication system. In the method, a received signal is converted into a signal of a frequency region. A noise signal is separated from the signal converted into the signal of the frequency region. A noise region is filtered by setting an occupied bandwidth from the signal having the noise signal separated therefrom. A DOA of the signal obtained through the filtering of the noise region is estimated.
