Robustness of OFDM under jamming
Hi all, I am working on a research on jamming. My victim link is the example GNu radio OFDM link. However the problem is even if I just use a Gaussian noise jammer (2 Mhz bandwidth) to jam this link (400 khz bandwidth), the link dies very soon at JSR = -5 db (basically this mean the jammer’power is 5 db weaker than the victim transmitter’s)
So have I had any problem with my hardware? I use the same usrp and daughterboards for jammer and victim, and I believe the tx power of jammer maybe a 1-2 db different but the barrage jammer should only win at jsr > 0 as I suppose.
Thanks for reading.
