Proposed Scheme for INR < SNR
Split each user’s signal into two streams:
Common information to be decoded by all.
Private information to be decoded by own receiver and appear as noise in the other link.
Set private power so that it is received at the level of the noise at the other receiver
(INRp = 0 dB).
Each receiver decodes all the common information first, cancel them and then decodes its own private information.
