Abstract :
We develop a technique for identifying the interference subspace in a signal plus interference plus additive white Gaussian noise model. Using this technique we propose a direction of arrival (DOA) estimator for uncorrelated signals impinging on a sensor array. Numerical examples are presented suggesting the superiority of this technique over MUSIC.
