FSKMOD Frequency shift keying modulation
Y = FSKMOD(X,M,FREQ_SEP,NSAMP) outputs the complex envelope of the
modulation of the message signal X using frequency shift keying modulation. M
is the alphabet size and must be an integer power of two. The message
signal must consist of integers between 0 and M-1. FREQ_SEP is the desired
separation between successive frequencies, in Hz. NSAMP denotes the number
of samples per symbol and must be an integer greater than 1. For two
dimensional signals, the function treats each column as one channel.
Y = FSKMOD(X,M,FREQ_SEP,NSAMP,FS) specifies the sampling frequency (Hz).
The default sampling frequency is 1.
Y = FSKMOD(X,M,FREQ_SEP,NSAMP,FS,PHASE_CONT) specifies the phase continuity
across FSK symbols. PHASE_CONT can be either 'cont' for continuous phase,
or 'discont' for discontinuous phase. The default is 'cont'.
