Executive Summary

In this paper, the authors analyze the performance of Distributed Network-Channel coding (DNCC) with Multiple Destinations executing a Code Nulling (MDCN) process. By analyzing the formulation deduced from DNCC with the MDCN process, they find that some unstable zero elements and additional noise are generated after right multiplying the parity-check matrix. These unstable zero elements and additional noise are the reasons to degrade BER performance in the Two groups of Source nodes and Two Destination nodes (TSTD) network model. Theoretical Bit Error Ratio (BER) curves are drawn according to the calculated equivalent received Signal-to-Noise Ratio (SNR).
