What does the DSP not do in a modern DSP radio?

In a modern DSP radio, the digital signal processing handles everything after the RF front end: converting the received signal to baseband, applying filters to shape the passband and reject noise, and performing the demodulation or detection to recover audio or data. It can also adapt to different modulation types in software, and implement features like automatic gain control and signal analysis. What it does not do is control SWR. Standing wave ratio depends on how well the transmitter is matched to the antenna, which is determined by the antenna tuning/matching hardware and impedance seen by the transmitter. The DSP doesn’t set or adjust that impedance; it operates on the digitized signal once the RF front end has done its job.
