Hi guys,
Can anyone help me in calculating the attached integral.
N=8,
a = 0:10 (dB)
x = sqrt(2*a)
and the goal is plotting PB vs. x.
TIA!!!!

Have a read here (or here for more general advice). It will greatly improve your chances of getting an answer.

Hi Su,
the inner integral (the one that is taken to the N/2-1 power) is
normcdf(v+X) - normcdf(-(v+X))
which is also
2*normcdf(v+X) - 1
assuming that v+X >= 0. But the lower limit on the outer integral, v >= -X, assures that this is the case.
So you can plug in either of those two expressions and then you are at least down to a single integral, which can be done numerically.
