Re: How to convert complex float file to complex int 16 in Gnuradio For USRP input...

I don't know what "don't acceptable" would mean in this context. The USRP accepts any int16. The fact that your signal is all zeros seems to be a problem with your signal; have you maybe scaled it incorrectly, so that it (correctly) gets rounded to all 0? Best regards, Marcus On 05.07.22 08:

Hey Yao, super happy to have you! I think that building software something does not work out as planned is a very common experience for many software developers :) The cool think is that you're working with Marc on this! I really can't wait until we can do fast GNU Radio in the browser, for

Thanks, This means when I send a complex signal I see it on spectrum, I too send a converted signal and I see a converted signal on the spectrum. Signals are not the same... I expect that signals in two formats (format int16 or float 32 ) be the same on a spectrum. I only have a signal in two forma

again, if your conversion yields all-zero values, you're not scaling appropriately. Best regards, Marcus On 05/07/2022 12.24, sp wrote: Thanks, This means when I send a complex signal I see it on spectrum, I too send a converted signal and I see a converted signal on the spectrum. Signals are

Regarding the .grc file.

Dear Sir, Could you please provide me the .grc file of development of GNU Radio Blocks for Spectrum Sensing Based on the Analysis of the Autocorrelation of Samples. I also searched for the different detector blocks like energy detector, cyclostatiinary etc, but I didn't find any block in gnu rad

Hi Sumit, no need to be so formal! Also, we're definitely not all "Sirs" on this list, there's quite a few ladies and others around here, and we're not just one guy. A simple "Hello!" suffices as greeting :) Welcome here! Well, spectrum sensing is a big topic, and a lot of it is based on auto
