Hi Team,
Can you please help with this inquiry?
I want to know how signal and image band energy monitoring are done because when I am trying to reproduce some result from one of your colleagues paper I am not able to Paper title is Interference Detection in FMCW Radar Using A Complex Baseband Oversampled Receiver
I am trying to reproduce one algorithm which you are using on the RF chip of the sensor SoC
some more details about this question: Your paper I mentioned above tells in Figure 10 about Hilbert transform and when I do this in Matlab to reproduce I see signal in both positive and negative freq although I should see only in positive freq : x=1:0.2:10000;
sino=exp(j*x*3);
design_hilbert = fdesign.hilbert();
Hd = design(design_hilbert,'equiripple','SystemObject',true);
calc_hilbert_imag=Hd(imag(sino));
calc_hilbert_imag_minus=calc_hilbert_imag*(-1);
neg_freq=calc_real+calc_hilbert_imag;
pos_freq=calc_real+calc_hilbert_imag_minus;
plot(abs(neg_freq))
plot(abs(pos_freq))
plot(abs(neg_freq))
Let me know if you need more information.
Regrds,
Marvin
