Abstract: Based on the architecture of the signal data matrix and generalized eigen value decomposition of its transformed matrix pencils, a novel and computational efficient method for separately estimating multiple two-dimensional sinusoidal frequency is proposed in this paper. Moreover, the estimated two-dimensional sinusoidal frequency is paired automatically. Its effectiveness is compared with eigen matrix transform method and confirmed by computer simulation.
