Hi there! You should also download the gr-osmosdr module which will then provide you with the osmocom source block which you will use with your rtl device You can find more instructions here https://osmocom.org/ projects/sdr/wiki/rtl-sdr Στις 24 Ιουλ 2017 20:32, ο χρήστης "Nipun Pruthi" έγραψε:

[Discuss-gnuradio] Pass boolean parameter to gnuradio script from command line

2017-07-18 Thread George Vardakis
Hi all! I need to give the user the option to pass a boolean parameter when executing my script from command line, something like '--split-image=True', where split_image is a parameter of a block. What is the way to do that from gnuradio without needing to translate inside my code the 'True' strin

[Discuss-gnuradio] Clock recovery without change of phase

2017-06-14 Thread George Vardakis
Hi all, I need to perform clock recovery on a signal without constantly changing its phase. I think that the clock recovery block in Gnuradio does exactly that in order to maximize the energy of the signal. Is there any other way that does not tamper with the signal phase? Thanks! ___

n the same usrp transmits and receives. This calls for some clock recovery function. Thank you very much for your time Marcus Στις 14 Ιουν 2017 10:55 π.μ., ο χρήστης "George Vardakis" < vardakis@gmail.com> έγραψε: Στις 13 Ιουν 2017 10:22 μ.μ., ο χρήστης έγραψε: In the two-USRP

Hello all, I have two USRP B210 devices which i use in my MIMO application. When i use the two of them concurrently in a flowgraph - or different flowgraphs - i notice that the signal received by the streams of one of the devices (the one whose serial number is last in lexicographical order) is di
