Pe = 0.5*erfc(√(Eb/No)); for BPSK Is this right? Thank you.

Click to expand... Err in the presence of additive gaussian noise? I'm plotting the simulated value ( with awgn added to it ) against the theoretical value. 1)Am i right to plot with the simulated value with theoretical equation in the first post? 2) Does anyone know where this equation comes from : Pe = 0.5 erfc(sqrt(10^(g/10)/2)) Is this equation similar to Pe = 0.5 erfc(sqrt(Eb/No)) Hehe I'm confused. Thank you
