文摘

Joint estimation of DOA and coefficients of PPS that impinge of uniform linear sensor array has been considered. A low complexity method for joint estimation of DOA and PPS coefficients has been proposed. It is inspired by recently proposed QML-based estimator of PPS coefficients. The method outperforms state-of-the-art techniques in terms of mean squared error and SNR threshold.
