To overcome the inter-carrier interference (ICI) of orthogonal frequency division multiplexing (OFDM) transmission subject to unknown carrier frequency offset and multipath channel, Vandermonde constrained tensor decomposition based blind approach is investigated in this paper. The main idea is that signal reception model is formulated as a tensor decomposition framework involving a Vandermonde structure...
In this paper, we propose a novel algorithm for underdetermined blind identification problem in blind source separation. The proposed algorithm is based on the charrelation matrix of observed signals. The charrelation matrix not only can be considered as a generalized second-order covariance matrix, but also incorporates higher-order information. It is significant for blind separation problem based...
