Abstract :
We propose an interference resistant angle of arrival estimation algorithm for OFDM systems with antenna arrays. We present an ESPRIT-based angle of arrival estimation algorithm for each multipath without training sequences after the signals with the phase shift invariant property are formulated by the proposed processing schemes.
