Khalil,
Here are some concepts you need to understand the capabilities of GNU
Radio:
- Complex Numbers, Negative Frequency
- Digital signal processing
- Frequency/Phase/Timing Offsets
- Sampling rates / sampling theorem
1) Study the https://wiki.gnuradio.org/index.php/SuggestedReading topics
on modulation and SDR.
2) If you have worked through the QPSK tutorial
https://wiki.gnuradio.org/index.php/Guided_Tutorial_PSK_Demodulation,
study each block in the flowgraph to determine what it does.
https://wiki.gnuradio.org/index.php/Category:Block_Docs has
documentation on every GR block.
3) If you have a specific / detailed question on an item, help can be
found in a number of places, such as:
- the search box in https://wiki.gnuradio.org/
- search engines such as Google
- search the https://lists.gnu.org/archive/html/discuss-gnuradio
Enjoy learning about SDR and GNU Radio!

Hello Everyone,
I hope everyone is doing well. I have a request to ask you guys.
I need to generate a baseband signal (I-Q) by using digital modulation
techniques like QPSK. I did generate the signal. However, I do not have
that much basic about how does it actually working. From source to sink
points. I follow-up on the tutorial but still do not get the real idea
behind it ( mapping points, amplitude, frequency, pulse shaping and
etc).
So my request is to you how can I get these ideas behind it in prospect
to GNU Radio. I did read something from books on digital modulation but
I found myself a bit different ideas with GNU Radio.
Would anyone like to share some documents on that with the related
environment with GNU Radio of course. Thank you in advance.
Sincerely,
Khalil
