There are many of them such as GPRSIM and the rest, but i think you can write your own programming code (using Python, C++ or Java) which will be an outstanding research work.

thanks mr kehinde but how

I think MATLAB may be a good choice. Anyway, please check the following:

thank you so much ms noha contrubing in this discussion

You can use MATGPR, Madagascar or MATLAB. They will do the job

Thank you s much
