anabpsk

Purpose

Binary Phase Shift Keyed (BPSK) signal.

Synopsis

[y,am] = anabpsk(N)
[y,am] = anabpsk(N,ncomp)
[y,am] = anabpsk(N,ncomp,f0)

Description

anabpsk returns a succession of complex sinusoids of ncomp points each, with a normalized frequency f0 and an amplitude equal to -1 or +1, according to a discrete uniform law. Such signal is only 'quasi'-analytic.

Name	Description	Default value
N	number of points
ncomp	number of points of each component	N/5
f0	normalized frequency	0.25
y	signal
am	resulting amplitude modulation

Example

         [signal,am]=anabpsk(300,30,0.1); 
         subplot(211); plot(real(signal));
         subplot(212); plot(am);
