I'm conducting experiments on several n-ary Psk signals of differing symbol rates. I'm comparing detection levels of different signal detection approaches on sets of PSK signals. I'm using a cosine-roll-off filter with a roll-off-factor of between 0.2 to 0.5.
To determine the appropriate signal to noise ratios, I had to decide which bandwidth I was gonna use. For reasons of practicality, I'd like to use the approximation symbolrate[bd] equals bandwidth[Hz]. It was proposed in chapter 6.2.4 of the book:

Do I act reasonably and doesn't it skew my evaluation with inappropriate error levels?
