  • Abstract
    Joint diagonalisation (JD) is an effective tool in many signal processing applications. A non-unitary JD method is proposed to estimate the two- dimensional (2D) frequencies. Experiments show that the proposed algorithm achieves good performance and the estimated 2D frequencies can be paired automatically.
