anafsk

Frequency Shift Keying (FSK) signal

Calling Sequence

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

Parameters

N:

a positive integer: the signal length.

NCOMP :

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

NBF:

a positive integer: the number of distinct frequencies (default: 4).

Y:

a complex column vector of length N: the signal

IFLAW:

a real column vector of length N: the resulting instantaneous frequency.

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.

Examples

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