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:

a real or complex Nx elements real (auto-Untenberger) or a Nx by 2 array signal (cross-Untenberger).

TAU :

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

N :

a positive integer: the number of frequency bins (default is Nx).

TRACE :

A boolean (or a real scalar) if true (or nonzero),the progression of the algorithm is shown (default : %f).

'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:

row 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');
