anafsk

Purpose

Frequency Shift Keyed (FSK) signal.

Synopsis

[y,iflaw] = anafsk(N)
[y,iflaw] = anafsk(N,ncomp)
[y,iflaw] = anafsk(N,ncomp,nbf)

Description

anafsk simulates a phase coherent Frequency Shift Keyed (FSK) signal. This signal is a succession of complex sinusoids of ncomp points each and with a normalized frequency uniformly chosen between nbf distinct values between 0.0 and 0.5. Such signal is only 'quasi'-analytic.

Name	Description	Default value
N	number of points
ncomp	number of points of each component	N/5
nbf	number of distinct frequencies	4
y	signal
iflaw	instantaneous frequency law

Example

         [signal,ifl]=anafsk(512,64,5); 
         subplot(211); plot(real(signal)); 
         subplot(212); plot(ifl);
