Clustering and labeling of orthogonal signals for modulation identification
説明
The increased demands for wireless communications lead to the development of cognitive radio, which realizes an effective utilization of channel resources. A modulation identification takes an important role in cognitive radio. In this paper an identification method is discussed for block orthogonal modulations expressed by general orthogonal modulation. The identification requires a reconstruction of signal-hypercube in a multidimensional space. The clustering and labeling methods are proposed for block orthogonal signals, and are evaluated from the view points of clustering error rate and labeling error rate.
