DOA estimation of signals with frequency characteristics and different powers using a compressed sensing technique

In recent years, much attention has been paid to direction of arrival (DOA) estimation using a compressed sensing technique. In our previous study, we have proposed a method to estimate DOAs of multi-band signals with frequency characteristics. However, we have assumed that all the arrival waves have the same amplitude. In this paper, we propose DOA estimation of signals with frequency characteristics and different powers among the arrived signals. Furthermore, we evaluate the method regardless of whether we know the frequency characteristics in advance.
