Both are pretty much unrelated. SNR you will be able to get based on your demodulation on the host. RSSI is based on the gain settings you choose for your amplifiers. The incoming power as seen by the ADC can be seen as the magnitude squared of your complex signal which determines how much dynamic range you are using of your ADC. In general, signal strength is a measure of how much energy you're converting (both signal and noise) whereas SNR is a measure of the quality of your signal with respect to noise (aka, a measure of how much converted energy is useful). I hope this is helpful. Brian _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
