Real-valued off-grid DOA estimation based on fourth-order cumulants using sparse Bayesian learning in spatial coloured noise

Meihong Pan, Gong Zhang, Zhentao Hu, Qin Zheng

Abstract: In this study, the authors address the problem of off-grid sparsity-inducing direction-of-arrival (DOA) estimation in the context of real-valued fourth-order cumulants (FOC) in the presence of spatia...
