Simultaneous diagonalisation of the covariance and complementary covariance matrices in quaternion widely linear signal processing

Abstract

Recent developments in quaternion-valued widely linear processing have established that the exploitation of complete second-order statistics requires consideration of both the standard covariance and the three complementary covariance matrices. Although such matrices have a tremendous amount of structure and their decomposition is a powerful tool in a… (More)
