Harmonics Retrieval Based on Quaternion Matrix

摘要：

This paper presented a novel method to estimate harmonicsparameters with quaternion.First,a kind of quaternion model of harmonic was established.Then,its correlation matrix,a quaternion correlation matrix (QCM),was constructed.Finally,this QCM was decomposed,where quaternion noise subspace was used to estimate harmonics parameters.Simulations illustrated this special idea and showed that frequency resolution of this method was better than that of classical MUSIC method.
