Hi Kevin, Thank you for your suggestions. Also I apologize for asking about this over the weekend, I think there is still a lot for me to learn at this time. One more question that I have is, a lot of the examples , such as the tx_stages use protocol formatter, which I think it's at a

Hi Lannan: It’s not that hard and only takes a few blocks: I suggest sticking with it as that’ll be easier than developing your own solution, plus it’ll be compatible with others down the road. My own radio isn’t working yet but it is very close, so I am going to study things a bit more and

Also, it would be super awesome if you could avoid posting question both here and on usrp-users without telling the other list; that can save people time not duplicating answers others have given already. On 25.07.20 10:42, Paul Boven wrote: > Hi Koyel, > > I was attempting to explain why the

Hi Koyel, I was attempting to explain why the output of the USRP block (Complex Int16) doesn't directly connect to other blocks. Although no other block in GNU radio seems to use the type 'Complex Int16', it is actually just a vector of size 2, containing the I and Q samples as 16 bits int.

Hi Paul, Thanks for your help. Can you please give an example? Like if usrp source outputs 16 bit complex as I Q I Q I Q I Q for 4 IQ samples where I and Q are 16 bit complex then what will be the change in the format after vector to stream conversion? I understood that usrp source block

Hi Kyeong, Will there be packet drops if USRP source is set at 32 bit complex float in grc when receiving at 100 MSPS each from two channels? That makes 2*100e6*64 (32 bit I and 32 bit Q) = 12800e6 or 12.8 gbps. I am unable to set usrp source block to 16 bit complex as then the usrp source
