How to find / create good propagation models

[tompak]

Hi,

I am learning some signal propagation to be able to find a model (possibly create my own based on existing theory) to convert RSSI values into distance.

I have read about delay / doppler spread, coherence bandwidth / time, and stochastic distributions like Rayleigh, Ricean and Log-normal.

But I do not understand if these physical parameters are going to be combined with the distributions or if they are separate ways of creating models.


If someone could help me get my head around this and possibly give me a general approach how to find a good propagation model, I would be very thankful.

Best regards

Hi,

Have you checker this?

Hi,

Thanks for the answer.

He/she has the same problem as I am, just that my application will be outdoors. However that post do not explain neither how the physical parameters comes into the equation or how the stochastic distributions used :/

you can convert rssi to easily by analyzing link budget , here is link to get good link budget tool
