Fred,
Isn't that what the RF Gain control or input attenuator is used for?
The ADC does not simply clip, when it overloads, the ADC output becomes
total garbage.
In other words, I don't know of any reasonable answer. To my mind, the
ADC determines the maximum usable dynamic range. If the strong signals
overwhelm the ADC maximum signal levels, no signals can be successfully
demodulated.
Mathematically, the overload situation might not be considered, but with
practical devices (ADC), overload is quite possible.

Question from a mathematics major [whose parents wanted him to be a EE]:
In a direct-sampling receiver, how do you control the input level to
the ADC to achieve maximum available dynamic range without clipping at
the ADC?
