IQ Demodulator

The IQ Demodulator can extract/demodulate a new signal(s) from an IQ stream:

IQ Demodulator Block

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:

Typical Mission:

How 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?

There is no limit from the software.

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