Full-diversity network coding for two-user cooperative communications
João Luiz Rebelatto, Bartolomeu Ferreira Uchoa-Filho, Danilo Silva · 2011
In this work, network coding is employed to obtain maximum diversity order in a network where the users have independent information to transmit to a common base station. We elaborate on the recently proposed generalized dynamic network codes (GDNC), which can only achieve part of the maximum diversity order when the inter-user channels are subject to outages. In particular, by allowing the users to perform network decoding, in this paper we show that maximum diversity order can be achieved. Results are restricted to the 2-user case, although some discussion regarding the general case is provided.
