Accuracy Limit in Separating Mixed Analogue Signals
Kazuo Yamanaka, Naoya Yamaguchi, Teruyuki Miyajima · IEEJ Transactions on Electronics Information and Systems · 2004
Accuracy limit is considered in separating mixed two analogue signals. A symmetry property is found in the estimation errors. The separation accuracy can be evaluated by extracting the non-causal component from a certain transfer function.
