Abstract :
The cross-Teager-Kaiser energy operator for complex-valued signals is defined and a new operator called ΨB is introduced. The relationship between the cross-Wigner-Ville distribution and the operator ΨB is established. This link results in a simple way to estimate the second conditional moment via the Wigner-Ville distribution. Some important properties of ΨB are also presented.
