John, Thanks for replying. The question is, how do I do this? We both agree the zeros need to go. What I'm not sure on is how to do that. I'd rather keep this contained to GRC, because I don't like maintaining python files not connected to grc. Can you explain how you do this or provide an example

I have another question on tag placement for the correlation estimation block. In the screenshot I've attached, you'll see that the corr_start tag is placed well before the preamble actually starts. If I use the 'delay tag' field to move it to the end of the preamble where I need it, it stops delay

Short answer: use corr_est as your tag. The corr_start tag is undelayed by the matched filter length, and intended for other purposes (data-aided equalizers, etc.). Andy Walls can say more, but it's enough to say the later three tags are the ones that match the peak of the correlation in the output

2015-04-22 Thread Richard Bell
Hello all, I'm using GR 3.7.8. I'm trying to work the new Correlation Estimation block into my design. I'm seeing what looks like unintended behavior for the tag placements. Sometimes the corr_start tag is placed on the same sample as the corr_est, time_est and phase_est tags, but sometimes the co
