Hi Ly, you might consider as an alternative solution shifting the frequency by multiplying with a sine wave if your application can sample at high rate. - "Nguyễn Văn Lý" wrote: > Hi Marcus, > > I use bladeRF hardware, not USRP. So I have "osmocom" sink and source > blocks in my flow graph

Hi Marcus, I use bladeRF hardware, not USRP. So I have "osmocom" sink and source blocks in my flow graph. Do you have any idea about this. Thank you very much, Best Regards, Van-Ly Van-Ly Nguyen, Research Assistant, Signals and Systems Laboratory - SSL Faculty of Electronics and Telecommunicat

Hello Van-Ly, what hardware are you using? If you're using any USRP, then the gr-uhd [1] blocks [2] will allow you to tune using stream tags, asynchronous messages and method calls. >From your problem description, it sounds like using stream tags is your best choice. If you want to know more about

Hello everyone, Does anyone know how to change Tx frequency during transmission. I mean the transmitter operates at f0 GHz in some interval of time and then change to operate at f1 GHz. Sincerely, Van-Ly Van-Ly Nguyen, Research Assistant, Signals and Systems Laboratory - SSL Faculty of Electroni
