Conclusion

We present a simple scheme that achieves within one bit of the interference channel capacity.

All existing upper bounds require one receiver to decode both messages and can be arbitrarily loose.

We derived a new upper bound that requires neither user to decode each other’s message.

Results have interesting parallels  with El Gamal and Costa (1982) for deterministic interference channels.
