HF Channel modeling in Propsim

Question asked by casturgeon on Mar 22, 2018

Hi

 

has any one got any experience of using the Propsim F32 for the modelling HF channels as per ITU-R F.1487 (see attached) ?

 

I'm specifically looking how to model the required frequency spread of the taps, I've tried using the Doppler spread property of the tap but it doesn't seem to allow me to input a number other than 0!

 

My other thought was to use the Gaussian fading model but that doesn't allow me to input a Std Dev of greater than 1 sigma whereas the spread i'm trying to achieve is 2 sigma according to 1487.

 

Any help greatly appreciated.

 

Thanks in advance
