Minimizing the sum of ℓ∞ norms enables separation of antisparse bounded sources via PCA followed by Givens rotations optimization, with claimed superior performance over prior methods in simulations.
However, it is important to note that the condition g1 +g 2 +g 3 = 1 came from the time instantsn 0 andn 1, where the 3 sources assumed the values (A, A, A) and (−A,−A,−A)
