New quantum receiver the first to detect entire radio frequency spectrum
What sort of exotic signal processing solution would be required to support 20GHz of bandwidth at any useful sampling rate and bit depth? How would you actually collect a meaningful amount of information from every station in range simultaneously?I feel like this is something that may be possible in physics, but is not well supported in practical applicability. The amount of signal processing hardware required to support this in the field should be a deal breaker with modern hardware, unless there are some really strong constraints regarding the bands & modulation schemes actually being monitored simultaneously.Assume 40GHz sample rate for bare minimum no aliasing over the 20GHz spectrum, 8 bits per sample. You will wind up with ~320Gbps of data to deal with.
