Enhance Degrees of Freedom for Coprime Array Using OptSpace Algorithm
IEEE Access, 2019 Coprime arrays, consisting of two subarrays with a co-prime number of physical sensors, can effectively resolve the direction-of-arrival (DOA) estimation when the number of sources exceeds the sensors. However, the conventional coprime array direction of

Direction of Arrival Estimation of Generalized Nested Array via Difference–Sum Co-Array
Sensors, 2023 To address the weakness that the difference co-array (DCA) only enhances the degrees of freedom (DOFs) to a limited extent, a new configuration called the generalized nested array via difference–sum co-array (GNA-DSCA) is proposed for direction of ...

COARRAY MANIFOLD SEPARATION IN THE SPHERICAL HARMONICS DOMAIN FOR ENHANCED SOURCE LOCALIZATION
, 2022 The order of a three-dimensional wavefield captured by a spherical array is limited by the number of sampling points i.e. the number of sensors in the array. This restricts the source localization performance of existing techniques for a spherical array.
