tfrridbn

Reduced Interference Distribution with a binomial kernel.

Calling Sequence

[TFR,T,F]=tfrridbn(X)
[TFR,T,F]=tfrridbn(X,T)
[TFR,T,F]=tfrridbn(X,T,N)
[TFR,T,F]=tfrridbn(X,T,N,G)
[TFR,T,F]=tfrridbn(X,T,N,G,H)
[TFR,T,F]=tfrridbn(X,T,N,G,H,TRACE)
[TFR,T,F]=tfrridbn(...,'plot')

Parameters

X :

signal if auto-RIDBN, or [X1,X2] if cross-RIDBN.

T :

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

N :

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

G :

time smoothing window, G(0) being forced to 1. (default : Hamming(N/10)).

H :

frequency smoothing window, H(0) being forced to 1. (default : Hamming(N/4)).

TRACE :

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

'plot':

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

TFR :

time-frequency representation.

F :

vector of normalized frequencies.

Description

tfrridbn Reduced Interference Distribution with a kernel based on the binomial coefficients. tfrridbn computes either the distribution of a discrete-time signal X, or the cross representation between two signals.

Examples

sig=[fmlin(128,.05,.3)+fmlin(128,.15,.4)]; tfrridbn(sig,'plot');
