Piggybacking Codes for Network Coding: The High/Low SNR Regime
arXiv:1704.05916
Abstract
We propose a piggybacking scheme for network coding where strong source inputs piggyback the weaker ones, a scheme necessary and sufficient to achieve the cut-set upper bound at high/low-snr regime, a new asymptotically optimal operational regime for the multihop Amplify and Forward (AF) networks.
