Multiway Physical-Layer Network Coding via Uniquely Decodable Codes
2018
Wireless Communications and Mobile Computing
Preserved Fulltext
We focus on a multiway relay channel (MWRC) network where two or more users simultaneously exchange information with each other through the help of a relay node. ...
We propose for the first time to apply ternary uniquely decodable (UD) code sets that we have developed to allow each user to uniquely recover the information bits from the noisy channel environment. ...

A multiway relay direct-sequence code-division multiple-access (MR-DS-CDMA) system is proposed for exchanging information among a group of distributed mobile terminals (MTs). ...
Signals at the relay and the MTs are detected in the principles of minimum mean-square error multiuser detection (MMSE-MUD) or of the receiver multiuser diversity assisted multi-stage MMSE MUD (RMD/MS-MMSE ...
Additionally, there are some wireless networks, such as the wireless ad-hoc networks for video conference or multi-player gaming, which are designed motivating to share information among a group of distributed ...
