this is the code for orthogonal code divison multiple access

% Spreading::::::::::::::::::::
%%%%  Generate data/modulation Vector - called d %%%%%%%%%%%%%%

for n = 1:length(d)
    Spreaded_Data(:,1+(n-1)*length(code):n*length(code)) = d.*code;
end
% Scramble
Y = Spreaded_Data.*Scrambling_Code(1:length(Spreaded_Data));
