tfrrstan

Reassigned Stankovic distribution.

Calling Sequence

[TFR,RTFR,HAT] = tfrrstan(X)
[TFR,RTFR,HAT] = tfrrstan(X,T)
[TFR,RTFR,HAT] = tfrrstan(X,T,N)
[TFR,RTFR,HAT] = tfrrstan(X,T,N,H)
[TFR,RTFR,HAT] = tfrrstan(X,T,N,H,TRACE)
[TFR,RTFR,HAT] = tfrrstan(...,'plot')

Parameters

X :

analysed signal.

T :

the time instant(s) (default : 1:length(X)).

N :

number of frequency bins (default : length(X)).

G :

frequency averaging window

h :

stft window (default : Hamming(N/4)).

TRACE :

if nonzero, the progression of the algorithm is shown (default : 0).

'plot':

if one input parameter is 'plot', tfrrstan runs tfrqview. and TFR will be plotted

TFR, :

time-frequency representation and its reassigned

HAT :

Complex matrix of the reassignment vectors.

Description

tfrrstan computes the Stankovic distribution and its reassigned version.

Examples

sig=fmlin(128,0.1,0.4); t=1:2:128;
G=tftb_window(9,'hanning'); h=tftb_window(61,'hanning'); tfrrstan(sig,t,128,G,h,1,'plot');
