Homework Equations
probability of bit error → ##P_e=Q(\rho)##
##\rho = \frac{A_p}{\sigma_n}##
The Attempt at a Solution
Im not sure I understand what's going on in the figure for this question. I would think that the bit error would be the shaded regions correct? I might be able to figure something out for expressing it in terms of conditional probability but I don't think it would be 100% correct. On top of that I have no idea how to express them in terms of integrals.
Im kind of guessing here but would it be something like $$P_e=p(r|-a) \ + \ p(r|a)$$
Im thinking no...
Any help or hints are greatly appreciated!
