摘要：
A time-frequency distribution that produces high concentration at the instantaneous frequency for an arbitrary signal is proposed. This distribution may be treated as a variant of the L-Wigner distribution, but it also satisfies unbiased energy condition, time marginal, as well as the frequency marginal in the case of asymptotic signals. The presented theory is illustrated by examples.
