Abstract :
Using signal energy criteria, the best lower-dimensional representation of a signal set is given by its principal components (PC). A comparison with a previous method by Huber and Liu (1989) shows that the differences are small. However, the minimum distance loss in CPM is generally larger with the PC method; thus it is mainly of theoretical interest. Still, it provides an alternative to Gram-Schmidt approaches, e.g. in simulations
