3.核心代码

NUMS = 20000;
Bits = round(rand(1,NUMS)>=0.5);
f1 = 1;
f2 = 2;
Scale= 50;
t = 0:1/Scale:1-1/Scale;
As = 1;
%FSK
Bits0 = sin(2*pi*f1*t);
Bits0 = Bits0/sqrt(sum(Bits0.^2));
Bits1 = sin(2*pi*f2*t);
Bits1 = Bits1/sqrt(sum(Bits1.^2));
fsk = [];
for i=1:NUMS
if Bits(i)==1
fsk=[fsk Bits1];
else
fsk=[fsk Bits0];
end
end
