A necessary and sufficient condition for the blind identification of memoryless systems
Lang Tong, Victor C. Soon, Yih-Fang Huang, R. Liu · 1991
The blind identification of multiple-input and multiple-output memoryless systems is considered. It is found that the system is identifiable with respect to uncorrelated sources if and only if the source signals have a distinct spectrum. A blind identification algorithm that is computationally simpler than previous ones is developed.>
