Hi,

I starting a new project to implement a SFN core on DVB-T modulator for receving SFN network signal and transmit it. Does anyone have any experience about it :roll: ?

Kappasm.
 

SFN is modelled by increasing the delay spread. The channel model example can be: channel gains im dB [0 -3 -5 7 -20 -23 -25 -27] a single impulse response is replicated with an offset amplitude loss and offset delay. Channel delays can be: [0 usec 1 usec 2 usec 3 usec 10 usec 11 usec 12 usec 13 usec]. This means that the interfering signal coming from neighboring cluster can be modeled as a multipath component with an offset delay and attenuation.
