A general form of the Nth order complex-lag time-frequency rate distribution is proposed. A few interesting special cases are considered and analysed. The proposed approach can arbitrarily reduce the spread factor. Hence, it provides a high concentration even for signals with fast varying instantaneous frequency rate.
