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

2 views (last 30 days)
% 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.
