ambifunb

Narrow-band ambiguity function.

Calling Sequence

[NAF,TAU,XI]=ambifunb(X)
[NAF,TAU,XI]=ambifunb(X,TAU)
[NAF,TAU,XI]=ambifunb(X,TAU,N)
[NAF,TAU,XI]=ambifunb(X,TAU,N,TRACE)
[NAF,TAU,XI]=ambifunb(...,'plot')

Parameters

X :

signal if auto-AF, or [X1,X2] if cross-AF (length(X)=Nx).

TAU :

vector of lag values (default is -Nx/2:Nx/2).

N :

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

TRACE :

if 1, (default is 0) the progression of the algorithm is shown.

'plot' :

if input contains the string 'plot', the output values will be plotted

NAF :

doppler-lag representation, with the doppler bins stored in the rows and the time-lags stored in the columns. When called without output arguments, AMBIFUNB displays the squared modulus of the ambiguity function by means of contour.

XI :

vector of doppler values.

Description

ambifunb computes the narrow-band ambiguity function of a signal X, or the cross-ambiguity function between two signals.

Examples

sig=anabpsk(256,8);
ambifunb(sig,'plot');
