Sparse unmixing of hyperspectral data is an important technique which aims at estimating the fractional abundances of endmembers (pure spectral components). It is well known that enforcing sparseness becomes a necessary process in sparse unmixing methods. To better exploit the sparsity in hyperspectral imagery, a double reweighted sparse unmixing algorithm has been proposed. However, it focusses on...
In this paper, we design a novel estimate-and-forward (EF) protocol in multiple-access relay channels (MARCs) where two correlated sources transmit their information to the common destination with the help of a relay. With the application of network coding (NC) at the relay, the network-coded soft symbols contain redundant information due to the correlated sources, which can be compressed before being...
In this paper, a passive detection system composed by multistatic stations is studied. According to the basic principle of time difference location technology, an indirect measurement way of time difference of arrival (TDOA) is provided to avoid the difficulty of direct measurement. The theory derivation and simulation analysis show that the indirect way can achieve certain location precision to meet...
