Partial response differential network coding in two-way relay channels

A new kind of encoding as well as a linear differential decoding method is proposed in this article. A new model built in the TWRC (two-way relay channels) is presented, which involves partial response coding at the source and two different kinds of differential coding(the add-differential coding and the multiple-differential coding) at the relay. This article puts forward the demonstration of the linear differential decoding. In the decoding process, this new method can be used in both kinds of differential coding. It can be seen this method simplifies the decoding process and has its commonality.
