how to build a Simulink HDL block set for FREQUENCY SHIFTING process with a for loop in the MATLAB

% 5MHz carrier

fs = 7.68;

tdw=LTE5_3_1.waveform;

%% SHOLDER REMOVING

shape5_out = conv(tdw,shape5);

%% UPSAMPLING AND LOW PASS FILTERING

fs3 = 491.52;

up5_out = interp(shape5_out,64);

%% NCO operation

fc4 = 40; %shift by 40 Mhz

for ii = 1:length(up5_out)

carr_1shifted(ii) = up5_out(ii).*exp(1i*2*pi*fc4/fs3*ii);

end

The NCO HDL Optimized block along with a multiply block can be used to generate the shift.

please can you give a guidance how to perform the procedure with the above code given. please it would be huge help

[Fayaz]

there no proper guidance to perform this. i think this has to be done with the use of lookup table, isnt it? can you help me becasue the my submission is around the corner
