Hello Martin,
Thank you for your response.
Could you tell me how can I solve the problem with the offset between the DPSK mod and demod?
In the same way, how can I garantee that I am comparing the correct bits? Using another block?
Likewise, as you say, I am using a packet-based transmission. For this reason I need to perform more sophisticated comparisons to calculate the BER, what do you recommend me to calculate BER?
Thank you all,
Antonio
