Superposition Coding Is Almost Always Optimal for the Poisson Broadcast Channel
Superposition Coding Is Almost Always Optimal for the Poisson Broadcast Channel
This paper shows that the capacity region of the continuous-time Poisson broadcast channel is achieved via superposition coding for most channel parameter values. Interestingly, the channel in some subset of these parameter values does not belong to any of the existing classes of broadcast channels for which superposition coding is …
