anafsk

Frequency Shift Keying (FSK) signal.

Calling Sequence

[Y,IFLAW]=ANAFSK(N,NCOMP,NBF)

Description

simulates a phase coherent Frequency Shift Keying (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.

Parameters

N :

number of points

NCOMP :

number of points of each component (default: N/5)

NBF :

number of distinct frequencies (default: 4 )

Y :

signal

IFLAW :

instantaneous frequency law (optional).

Examples

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