WebWhile traditional HOS methods in array processing mainly exploit higher-order cumulants of the received data, we propose a DOA estimation method based on the fourth-order moments, which is of lower computational load than the fourth-order cumulants. WebBased on sparse representations, the problem of two-dimensional (2-D) direction of arrival (DOA) estimation is addressed in this paper. A novel sparse 2-D DOA estimation method, called Dimension Reduction Sparse Reconstruction (DRSR), is proposed with pairing by Spatial Spectrum Reconstruction of Sub-Dictionary (SSRSD). By utilizing the angle …
WebFeb 27, 2024 · The DOA estimation accuracy for correlated signals is improved by employing distributed ML approach in this paper. The subarray formed at a particular node which is experiencing highest CRLB can improve its estimation accuracy by receiving better DOA estimates from its neighbors.
WebWe consider the problem of direction of arrival (DOA) estimation in the presence of multipath propagation. The sensor elements are assumed to be linear and uniformly spaced. To perform DOA estimation, we combine two existing algorithms which are often used for other purposes. The first algorithm exploits fourth-order cumulants to perform blind … WebApr 5, 2016 · We present an algorithm for two-dimensional (2D) direction-of-arrival (DOA) estimation of noncircular sources using an L-shaped sparse array. An L-shaped sparse array consisting of two co-prime arrays is firstly introduced.
