It is known that accurate partition of subspaces is important to fourth-order statistics based multiple signal classification (FO-MUSIC) algorithm. However, when the number of signals exceeds the number of array elements, the error of conventional subspace partition method will increase, and the performance of FO-MUSIC algorithm will decrease. A novel subspace partition method for FO-MUSIC algorithm...
In order to sort frequency hopping networks, the problem of estimating Direction of Arrival (dOA) of frequency hopping signals in underdetermined case is discussed in this paper. Inspired by the underdetermined blind source separation algorithm and product of hopping frequency and DOA in frequency hopping signals mixing matrix, a novel underdetermined DOA estimation method is proposed. Firstly, mixing...
In this paper, a new algorithm to suppress the interferences for Direction-of-Arrival(DOA) estimation is presented. The method is based on the property of the noise subspace invariant to power of emitters. With theoretical analysis and computer simulations, it is shown that the proposed method has a good performance on signal DOA estimation under disturbances.
This paper presents a novel real-valued multiple signal classification (RV-MUSIC) algorithm, which tremendously reduces the computation complexity than the complex one by a factor of four. The covariance matrix of the sensor output is firstly transformed into a real-valued covariance matrix via unitary forward/backward (FB) technique. Then the MUSIC algorithm in real domain is used to estimate the...
