Efficient Decoding Algorithms for the Compute-and-Forward Strategy [PDF]
IEEE Transactions on Communications, 2015 We address in this paper decoding aspects of the Compute-and-Forward (CF) physical-layer network coding strategy. It is known that the original decoder for the CF is asymptotically optimal. However, its performance gap to optimal decoders in practical settings are still not known.
