This scheme can correctly work for the underdetermined case where the number of signals is larger than the number of sensors, but it is unable to handle the coherent signals.
WebThe third-order measure is called the third-order moment M(m1,m2) = Note that the third-order moment depends on two independent lags m1 and m2. Higher order moments can be formed in a similar way by adding lag terms to the above equation. The signal cumulants can be easily derived from the moments.
