摘要：

The complex signal of two dimensional harmonics is common. The pairing steps are always needed when we estimated the frequency pairs of harmonics which is described by complex signals. First we construct the quaternion signal model through the separated signal and its Hilbert transform. Then we define the corresponding four-order cumulant to restrain the additive Gauss noise and extract the frequency. Some simulations prove the correctness of the algorithm in this paper.
