Also, your Polyphase Clock Sync is outputting 1 samples per symbol ("Output SPS"), while your equalizer is expecting 2 samples per symbol (If I understand the arguments correctly. Don't have GnuRadio intalled, and haven't used it myself) Laur 2017-04-13 1:40 GMT+03:00 Kacie O'Neil

Hi again, a few quick questions. How do you decide on the values of MIN_GAP(480) and Max frame size(540*80)? If during reception, one frame arrives within 480 samples of the other, say within preamble duration of the first, are the subsequent samples are copied anyway because the block is in

Just use: complex(math.cos(angle-in-radians),math.sin(angle-in-radians)) As the constant in a multiply-const block On 2017-04-18 10:23, Trejo Treviño wrote: > I am trying add a phase-shift to my signal via the use of a multiply block, > but I have not been able to find the correct inputs

[Discuss-gnuradio] Phase shift using a multiply block

2017-04-18 Thread Trejo Treviño , Fernando Alberto
I am trying add a phase-shift to my signal via the use of a multiply block, but I have not been able to find the correct inputs for the block. What syntax should I use to input an exponential or a complex cosine/sine combination for the multiplication? Best, Fernando
