Interference management via sliding-window superposition coding

The sliding-window superposition coding scheme achieves the performance of simultaneous decoding with point-to-point channel codes and low-complexity decoding. This paper provides a case study of how this conceptual coding scheme can be transformed to a practical coding technique for two-user Gaussian interference channels. Simulation results demonstrate that sliding-window superposition coding can sometimes double the performance of the conventional method of treating interference as noise, still using the standard LTE turbo codes.
