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?
