In 揚erformance of multi-carrier DS CDMA Systems?we apply a multi-carrier signaling technique to a di

function [y] = RCF(f,alpha,T,fc)
% ----------------------------------------------------------------------- %
if (abs(f-fc) > ((1+alpha)/(2*T))),
   y = 0;
elseif (abs(f-fc) > ((1-alpha)/(2*T))),
   y = (T/2)*(1+cos((pi*T/alpha)*(abs(f-fc)-(1-alpha)/(2*T))));
else 
   y = T;
end
