Re: Excess bandwidth in constellation modulator

Thank you for your reply with the details. I do already read from the GNU Radio tutorial but wasn't fully sure. The equation now clear, just want to make sure one point from you. After the modulation(e.g qpsk) signal upconverted to RF, then the signal bandwidth still will be the same? Thank you ag

Thank you Maitland. Is there a "safer" way of installing gnuradio 3.8? Matiland - there is not such a folder in /modtool/gr-newmod. I only have /usr/share/gnuradio/modtool/template On Tue, Feb 25, 2020 at 1:13 PM Maitland Bottoms wrote: > Laura Arjona writes: > > > 1 - Installed fresh Ubuntu 1

Thanks Brian. You are right, there exists three VCOs and PLLs in the AD9361 which can be controlled independently. AD9361 Reference Manual UG-570 shows a more detailed diagram in Figure 7. on page 20. The baseband PLL comprises an N/N+1 divider controlled by a high-precision sigma-delta modu

Hi Narayanan, welcome here and thanks for your interest in GNU Radio and gr-radar. To get started with Python I'd use one the countless resources you find on the web. After that you would probably want to study the code of gr-radar itself (the tests usually use Python). For a general introduction
