The BER error rate block does not realign data from its inputs.  Experiment with different delays between the reference tream and the demod stream to account for FIR filters, clock recovery process, etc.  Note, due to the nature of symbol recovery, the delay may not be the same every time.

Also, watch out for phase ambiguity in the BPSK demod.

 i was working in BPSK mod/demod and i'd like to see the BER performance. i used the BER ERROR RATE block, connecting in the input 1: random source and imput 2: output of the decodec. The problem is that the error always is 0.5 and the source noise (connected in the mod,) doesn't affect it.
