In this paper, we consider Digital Network Coded Cooperation (DNCC) with Decode-and-Forward (DF) relaying scheme in correlated environment. In order to quantify the performance of DNCC network, analytical closed form expression of the outage probability for Non-Line of Sight (NLoS) correlated environments is derived. For the sake of completeness and comparison, investigation of uncorrelated environments is also presented. Unlike existing investigations, it is observed that spatial correlation among channels considerably improves the performance of such networks. In particular, detrimental effects of the Digital Network Coding (DNC) noise is abated by the channel correlation. Additionally a discussion on various deterministic geometries for such networks is also presented to get further insights about node placement. Cumulative Distribution Function (CDF) obtained for Signal to Noise Ratio (SNR) of relay path can be utilized for performing diversity calculations. Outage closed form expressions derived may be used to choose network parameters judiciously in different NLoS correlated scenarios for achieving better Quality of Service (QoS) in next generation wireless networks.
