Thanks for the clever insights, Marcus. I'll consider the PMT vector approach you mentioned, while at the same time knowing PMT is likely to undergo changes in the future as you mentioned, I'll also look into using TCP/IP to pass the needed information, perhaps ZeroMQ or a UDP socket even. On Fri,

Hi Brad, so, yes, your observation is correct: PMT symbols are/were meant to be used as "identifiers", not as "data carriers"; the motivation behind the hash table you find in pmt.cc is that there's only one instance of any given PMT symbol, and thus, a simple address comparison suffices to tell w

Hi Batu, a really intuitive way of implementing FSKs is to convert your bit groups to baseband frequency values (e.g. -1.5, -0.5, 0.5, 1.5) and use them with the frequency mod block. Best regards, Marcus Marcus On Fri, 2019-03-01 at 16:59 +0300, Batu Kaplan wrote: > I am implementing the binary

[Discuss-gnuradio] Modulation order of FSK

2019-03-01 Thread Batu Kaplan
Hello everyone, I am trying to implement a text transmission with FSK modulations. I did my research about FSK on GNURadio, but what I found is mostly with binary FSK. I have a problem with designing the flow graph of M-FSK modulation. I am implementing the binary FSK with GFSK block and I think
