I would like to modulate in amplitude the upper and lower sides of a carrier with two distinct signals. Would it be possible? There is a specific name for this scheme of modulation?

The detection will be made using the sampled data (in the digital domain).

  • \$\begingroup\$ I think I should have said upper envelope and lower envelope modulation, as upper and lower carrier trend to direct the answers to sidebands topic. \$\endgroup\$ – H Krammes Apr 12 '18 at 12:58

Yes, look for ISB modulation (Independent side band modulation), the military used to do it carrying two separate message streams on the two sidebands.

I am not sure there is much benefit these days, but it is not much of a problem to do, two phasing method modulators and just sum the output before up conversion, easy.
