Suppose we have to receive in a wideband of 100Mhz (with noise floor computed of -94 dBm ) a digitalized rf signal which needs 10dB of CNR; so the minimum detectable signal is -84dBm. If signal has a BW of 1Mhz, can an ADC demodulate this in case it is below -90dBm?
In case my ADC has 16 bit (enob) and sample @10 Mhz with dBmFS=6dBm, this translate to 6-98+7=-85dB NSD, would it be theoretically enough?
Thanks
