Sorry, I was thinking of multiplexing using AM, where the sidebands would 
overlap adjacent channels if the modulating frequency is not band limited
to 
1/2 the carrier spacing (as it happens on the AM Broadcast band at night).
A 
single isolated AM transmitter would not alias into its own baseband.
