Two 2-D DOA Estimation Methods with Full and Partial Generalized Virtual Aperture Extension Technology
Published 2019-01-01“…For the sparse reconstruction method, first, we give a lemma to verify that the received data model is equivalent to its dictionary-based sparse representation under certain mild conditions, and the uniqueness of solutions is guaranteed by assuming azimuth and elevation indices to lie on different rows and columns of sparse signal cross-correlation matrix; we then derive two kinds of data models to reconstruct sparse 2-D DOA via M-FOCUSS with and without compressive sensing (CS) involvements; finally, the numerical simulations validate the proposed approaches outperform the existing methods at a low or moderate complexity cost.…”

Sparse Deep Nonnegative Matrix Factorization
Published 2020-03-01“…Such models are designed to learn localized features or generate more discriminative representations for samples in distinct classes by imposing L1-norm penalty on the columns of certain factors. By extending a one-layer model into a multilayer model with sparsity, we provided a hierarchical way to analyze big data and intuitively extract hidden features due to nonnegativity. …”
