Antonio, I'm not sure why it's telling you 'no BER', but your setup is not suitable to test BER anyway. Your DPSK demod will always be offset w.r.t the DPSK mod input (because of sync delays etc.).
Such BER measurements only work well if you can guarantee you're comparing the right bits. Since you're doing packet-based transmission, you'll need to come up with something more sophisticated comparison.
