Help in the codes for BER calculation

Hello,
I am glad to have help to find my mistake in this attached file for BER calculation code in TAS/MRC Full-duplex Amplfiy-forward theoretical values. The contents in codes are right but I am not sure about wordings or etc.
Thanks.

What is the issue? Are you getting an error? Any output at all? The wrong result?

Actually when I run the code, it seems as running to compute but neither an error occurs nor an output is created.

I have changed notations in code, but the result did not change. Neither gives an output nor an error just wait and no result,
Thanks.

The style of the cells in the notebook are Text. Text cells don’t evaluate. Code needs to be entered in Input style cells.

thanks for review and reply.
