Hi everyone, I am builing a bpsk receiver, I can receive my signal, demodulate it, find the marker of my packet (0x1acffc1d) and read it. Everything looks fine excpet when I try to find the marker of the packet. I have a delay that I don’t anderstand. I send a message every second and because of this delay, after some message a could have more thant 5 seconds delay at the reception of my data.
To detect de sync marker I use the hierachical block from Daniel Estevez ( thanks to him) found in gr-satellites. Using the control port performance, I see that the block « correlate acces code -tag » uses a lot of time. I don’t anderstand why this block slow down the all system. Is it because of the tag ? Or someone has another solution/workaround to remove this latency ? Thank you in advance, Sam
