In order to simulate a multi-path scenario, Im trying to validate the
“Frequency Selective Fading Model” block, but the results I found are
the ones I would expect.
The set up consisted of 2 taps delayed 20 microseconds each other, so
the frequency response should have very deep fadings spaced regularly in
frequency. The results I got showed a flat frequency response, as well
in other standardized power delay profile scenarios.
The blocks I used were a random source -> OFDM Mod -> Throttle ->
Selective Fading Model -> WX GUI FFT Sink. Sample rate was set as 1MHz,
that in Freq. Selective block I set PDP Delays as [0, 20] and PDP
Magnitudes as [1, 1].
Please tell me if I misunderstood any of these parameters or this block
could be really improved.
Thanks and Regards,
