BPSK Demodulate Bitstream Inverted

Hello,

 

i have one Problem with the Demodulation of the Bitstream.

 

Ich had design a BPSK Simulated Transmitter an Reciver. It generate a Bitstream --> then modulate --> then Upconvert it --> Downconvert it --> Demodulate ---> show Bitstream.

It's all ok, but my Output Bitstream are Inverted! Why? 

 

I use the MT Generate System Parameters.vi to create the Parameters for the Mod. and Demod. The Symbolmap is the same on the Demod. and the Mod. So i do'nt understand why it is Inverted. I tryed to set the Symbolmap manualy, but it dosn't bring any difference. 

 

Can anyone help me? 

 

Thanks.
