Hello everyone, I am looking towards how to make a flowgraph to detect when received signal strength is below -20 dB for instance. It'll automatically change modulation techniques to a low-order modulation (QPSK) and when more than -20 dB (say -10 dB). It'll take a high modulation technique (16QAM). May I know if anyone is working on this. I am willing to learn and contribute as well. Thank you.
