中文摘要：

这份报纸在多重存取隧道从网络观点在用户公平上调查网络编码的影响(NC ) 。第一，同时的停止作为度量标准被利用评估用户公平。优化它，一个面向公平的物理层 NC 计划被建议，在哪个用户的信号在继电器在特定的计算比例被附加然后由最大的比率联合(MRC ) 和连续干扰取消译码(原文如此) 在目的地。而且，同时的停止上的力量分配系数错误的影响也被分析与用户公平揭示它的关联。模拟结果显示建议计划能为每个参与合作的用户供应近似相等的表演提升并且没有公平考虑，以采用的度量标准超过那些。

英文摘要：

This paper investigates the impacts of network coding （NC） on user fairness from the network perspective in multiple access channels. Firstly, simultaneous outage is exploited as the metric to evaluate user fairness. To optimize it, a fairness-oriented physical layer NC scheme is proposed, in which users＇ signals are superimposed in specific calculated proportion at relay and then decoded by maximal ratio combination （MRC） and serial interference cancellation （SIC） at destination. Furthermore, the influence of power allocation coefficient error on simultaneous outage is also analyzed to reveal its correlation with user fairness. Simulation results indicate that the proposed scheme can supply approximately equal performance promotion for each cooperation-participated user and outperform those without fairness consideration in terms of the employed metric.
