If your question is not about this, please explain more. Regads, Chaker

CNR= Carrier to Nosie ratio, If the required bit rate is given, then baud rate will change with the modulation scheme. How can I calculate the required bandwidth?

It can help you http://sss-mag.com/ebn0.html About bandwidth there is different definition. In many cases we use the filter badwidth or canal bandwidth but in digital communication books we define bandwidth by other definitions. The famous one is null-to-null badwidth. This bandwidth depends on modulation schema : Take a look to the book : Digital modulation techniques : Fuqin xiong Regards Chaker
