Abstract


In this paper, a low complexity ESPRIT algorithm for coherently distributed noncircular source is proposed. Due to the utilization of noncircular source, the proposed algorithm derives both the received signal and its conjugate to obtain the extended received data matrix and covariance matrix. When compared to the conventional ESPRIT algorithm, the algorithm considering noncircular properties can provide more accurate estimation performance. Numerical simulation results verifies the validity and reliability of the proposed algorithm.
