An Iterative Network Code Optimization for Three-Way Relay Channels

We consider a three-way relay channel using a network coding in this paper. We propose a network coding scheme for the three-way relay channels and present a Latin square-like condition for the three-way network code. We also propose several schemes to design a new three-way network code by using the cell swapping and applied the methods to obtain a better network code to obtain a fair symbol error rates among the users.
