Max d,
The distinction is simple - If the carriers or tones which create the
bandwidth expansion (or spreading), are accomplished by means of a
spreading signal , i.e., a separate code signal, which is independent of
the data , then it is spread spectrum no matter what you would like to
call

Sorry, I meant to write, For example in SSB, the RF frequency at any
time is equal to the tone frequency of the voice plus the suppressed
carrier frequency (USB).
I did not mean the tone frequency at any time...etc.
