Re: [Discuss-gnuradio] Correlation Estimator Over the Air

​We saw a lot of improvement in the performance of the Correlation Estimator block once we calculated a level for the AGC. In our case, we're looking for a BPSK preamble that is a pseudorandom sequence. The corr_est block is provided with the match-filtered version of the preamble sequence. So

[Discuss-gnuradio] Audio bandwidth

Hi all, I have question related to audio bandwidth cutoff. Yesterday, I received very good signal from STRaND satellite 9600 bps, FSK modulation. I used audio sink to record the signal then used it for decoding. However, I was unable to decode signal, then I ask some another ham radio expert and

In some articles, they are referring uPHYLA which is a SDR framework like GNU Radio. But I don't see anything that tells download, installation, or documents. It first appears here. http://upcommons.upc.edu/bitstream/handle/2117/16551/110803-1569470189-45171.pdf?sequence=1 They say uPHYLA stands

Re: [Discuss-gnuradio] Correlation Estimator Over the Air

Sean, Thanks for the tip! Is the k value the reference value in the AGC2 block or the max gain? Would you mind explaining the equation you used a little more? From what I understand of it, the seq is the 1's and 0's that make up the pseudorandom preamble, N is the sequence length and i is the

Dear friends of GNU Radio, Google has announced they'll be doing another GSoC next year, and we intend to apply. Last year, we weren't accepted as an organization, partly because our ideas list wasn't up to par. That, at least, is something we can fix. Also, if ESA is doing another summer of
