WARNING: This is an obsolete function and may be removed in the future.

Please use PAMMOD, QAMMOD, GENQAMMOD, FSKMOD, PSMMOD

MSKMOD instead.

请教FSKMOD中的几个参数应该如何选取！

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) sp
