Subject: | [Discuss-gnuradio] latency to detect sync marker with "correlator block" |
Date: | Thu, 9 Aug 2018 17:16:24 +0200 |
Hi everyone,
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 |
