Design of superposition polar coding for binary-input less-noisy broadcast channels

Abstract

In this study, we design a superposition polar code that can achieve the capacity region of binary-input less-noisy broadcast channels asymptotically. Simulation results show that a better rate region is achievable by superposition polar coding than by time sharing between two point-to-point channel polar codes.
