Abstract

Recently, the network coding in cooperative communications has been categorized into two mainstreams, Digital Network Coding (DNC) and Analog Network Coding (ANC), which we both discuss in the article. First a brief survey of these two sub-branches is given. Then, to the very wireless characteristics fading and interference, DNC and ANC network coding way were proposed respectively, which aims at combating fading and embracing interference in wireless medium. Specifically, the idea of network-coded cooperative protocol in this paper is to combine different source nodes' information at the bit-level and signal-level corresponding to DNC and ANC in the relay node and then perform joint decoding in the destination node. The proposed DNC and ANC are demonstrated to obtain both capacity and reliability gains.
