Reassigned pseudo Wigner-Ville distribution
[TFR,RTFR,HAT] = tfrrpwv(X) [TFR,RTFR,HAT] = tfrrpwv(X, T) [TFR,RTFR,HAT] = tfrrpwv(X, T, N) [TFR,RTFR,HAT] = tfrrpwv(X, T, N, H) [TFR,RTFR,HAT] = tfrrpwv(X, T, N, H, TRACE) [TFR,RTFR,HAT] = tfrrpwv(...,'plot')
A Nx elements vector: the analyzed signal.
a real Nt vector with elements regularly spaced in [1 Nx] : time instant(s) (default: 1:NX).
a positive integer: the number of frequency bins (default: Nx). For faster computation N should be a power of 2.
real vector with odd length: the frequency smoothing window,(default: window("hm",N/4)).
It will be normalized such as the middle point equals 1 to preserve signal energy.
if nonzero,the progression of the algorithm is shown (default : 0).
if the last input parameter value is 'plot', tfrqview is called and the time-frequency representation will be plotted.
A real N by Nt array: the time-frequency representation.
A real N by Nt array: the reassigned time-frequency representation.
AN by Nt complex matrix of the reassignment vectors.
tfrrpwv computes the pseudo Wigner-Ville distribution and its reassigned version.
