摘要：
Using sparse component analysis for the blind recognition OSTBC signals, the method for blind recognition of real OSTBC based on SCA is proposed. The proposed algorithm first built the model of received signals and the virtual channel matrix, then the virtual channel matrix is separated by using the RCA algorithm. After that, by according the characteristics of real OSTBC, two characteristic parameters of correlation matrix of virtual channel matrix sparsity and energy of ratio of non main and main diagonal elements energy are proposed to recognize signals. ©, 2015, Binary Information Press.
