Universal Encoding Scheme for General Zig-Zag Network
Yanbo Yang, Feng Cai, Wangmei Guo, Fang Li · IEEE Communications Letters · 2014
In recent works, authors discussed upper bound for unequal capacity network called zig-zag network. It shows that there are several variants of upper bounds starting from cut set bound according to topology of the zig-zag network. We propose an universal coding structure, on which the same detection and decoding strategy can be applied to achieve any particular variants of cut set bound.
