I want to give signals in polar form...First I create random data and then use If condition to change it to polar form

len=128;

m=4;

msg1=randint(len,1,m);

msg2=randint(len,1,m);

if msg1(1,1)=0

polar_data=-1;

else

polar data=1;

end

if msg2(1,1)=0

polar_data2=-1;

else

polar data2=1;

end

In your if statements you need to use the symbol "==" rather than "=" to check equality.

There are a couple other errors in your code. For example, you have the line

polar data=1;

which I think you meant to be

polar_data=1;

Below, I fixed up a couple of those:

len=128;
m=4;
msg1=randint(len,1,m);
msg2=randint(len,1,m);
if msg1(1,1)==0
polar_data=-1;
else
polar_data=1;
end
if msg2(1,1)==0
polar_data2=-1;
else
polardata2=1;
end
