List Decoding for Bidirectional Broadcast Channels with Unknown Varying Channels

摘要: The concept of bidirectional relaying shows the potential to improve performance in wireless networks such as sensor, ad-hoc, and even cellular systems. It applies three-node networks, where a relay node establishes communication between two other nodes. In first phase decode-and-forward protocol, nodes transmit their messages node, which decodes them. succeeding broadcast phase, broadcasts re-encoded composition them so that both can decode other's message using own side information. We assume transmission is affected by unknown varying channels. Unfortunately, variation channel lead channels completely prohibit any reliable communication. this work, we analyze under list decoding show technique significantly sense it allows reliably scenarios usual schemes fail.
