IQ Demodulator

Quote from AdminTC on 08/03/2021, 16:57The IQ Demodulator can extract/demodulate a new signal(s) from an IQ stream:
Left hand side Input:
- IQ
Right hand side Output:
- IQ (extracted new IQ stream)
The IQ Demodulator block can extract/demodulate a portion or even multiple portions from an IQ signal. The center frequency and span incl. a new sample rate can be set as needed. An addition we have added a low pass filter, a bounds check and a processing latency control:
A typical mission: Two signals extracted from a single IQ signal for further processing:

Quote from ALPS on 27/12/2021, 07:15How many maximum individual signals can be extracted from a 80 MHz IQ stream (from V6 RF Input)? If I understand correctly, we need to add that many IQ demodulators in parallel - is there any software limit? Can you specify CPU core/RAM requirement on average for each IQ demodulator block?

The CPU and RAM load is quite low but try yourself on your local machine.

Quote from CorNic East on 10/05/2022, 18:37Can you provide more details on this block ...
Is this block actually demodulating or channelizing?
How are you performing the modulation recognition and do you (can you) provide a confidence level? Might also be nice to see some info on the clock recovery.
Would it be possible to allow entry of a specific demodulation (including symbol rate)?
What is actually coming out of the IQ output, an IQ stream of (packaged) symbols? If so, I would assume at the clock recovery rate and modulation format?
Would love to have some very detailed instruction on this block and it's operation bounds.
