—A novel wideband direction-of-arrival (DOA) estimation method is proposed for co-prime arrays. After decomposing the wideband signals into different frequencies/subbands through a discrete Fourier transform or, more generally, a filter bank system, the increased degrees of freedom provided by co-prime arrays are fully exploited with a group sparsity based(More)
A typical mechatronic product includes mechanical parts, software techniques, electrical and electronic components. This interdisci-plinary character significantly increases the complexity of mechatronic products. Therefore, inefficient communication between the engineers , who come from different domains, becomes one of the main challenges in the(More)
A class of low-complexity compressive sensing-based direction-of-arrival (DOA) estimation methods for wideband co-prime arrays is proposed. It is based on a recently proposed narrowband estimation method, where a virtual array model is generated by directly vectorizing the covariance matrix and then using a sparse signal recovery method to obtain the(More)
BACKGROUND Phthalates are a group of environmental endocrine disruptors and have been ubiquitously applied in industrial field. Few studies had investigated how dietary intake was related with phthalate body burden in children. To determine the relationship between phthalate body burden and dietary intake among school age children in Shanghai, China. (More)
