What is one exactly referring to when you say "baseband signal processing algorithms"? Can anyone give a few (common) examples.

  • $\begingroup$ This question is incredibly broad and open-ended, and hence not a great fit for this site. Maybe you can narrow down your question? Why are you asking this? What do you (not) understand about baseband signals? $\endgroup$ – Marcus Müller Aug 27 '19 at 19:43
  • $\begingroup$ "Baseband" means that the signal has no carrier; in other words, it has not been frequency-shifted. The opposite is "passband algorithms". Does that help? $\endgroup$ – MBaz Aug 27 '19 at 21:27

Baseband signal processing algorithms would refer to any algorithm that is written after you have down converted your RF or IF signals to baseband(signal centered around 0 Hz).

Example : Suppose there is a difference in the RF carrier frequency between the transmitter and receiver . So , after downconversion at the receiver , there will be a frequency offset (equal to Tx Center Frequency - Receive Center Frequency) in the baseband signal . In this case , an algorithm to estimate/correct this frequency offset on the baseband signal can be termed as a baseband signal processing algorithm.

Other baseband algorithms could include estimation/correction of Timing Offset and IQ Impairements to name a few.
