Theoretical BER with BERTool in Rayleigh channel

Hello,

I am using BERTool to compare the theoretical and simulated BER of a QAM modulation under a Rayleigh fading channel. I am using a "multipath Rayleigh fading channel" block in my Simulink model; the Doppler spectrum type and maximum Doppler frequency shift can be selected within this block. I would like to set this values to those used when the theoretical BER is computed. However I can't possibly find out what values are used by BERTool.

Any help on this would be very much appreciated.
