how to configure parameters for NCO(frequency shifting or frequency correction) simulink block set based on the NCO operation has performed in the matlab script

12 vues (au cours des 30 derniers jours)
i have to build the hdl block set for NCO(frequency shifting). so i selected a HDL NCO block, but i dont know how to set the parameter configuration according to my script. i have gone through the MATLAB simulink HDL guide, but i could not understand. i will attach the details of NCO block configuartion tab screen shots, if anyone can you help me to do that. please be kind enough to give a support
% 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

Please find attached a sample NCO block that can generate HDL code.

sir, can you give guidance to apply the parameters that i have mentioned in the question, to the NCO model that you have suggested. it is more complicated to understand how to apply them. pls be kind enough to give a support to me as i have no alternative method to get understand andalso im aound the corner of my final submission. please
