The result is an IS-95CDMA forward link software simulation package ,which mimics real-time data com

function info=Data(L)
%generate user data for a 20ms frame, there is 172 bits of information,12bits of CRC and 8 bits of Encoder tail

%We first generate the 184(information +CRC) bits using the randn function then
d=randn(1,L-8);
%then we perform the function a decision device any bits below 0 then we make it a 0 else a 1

for (i=1:L-8)
   if(d(i)>=0)
      d(i)=1;
    else
      d(i)=0;
   end
end
%add 8bits of encoder tail which the viberti decoder can dectect.
info=[d,0,0,0,0,0,0,0,0];
