摘　　要：从信息论的角度研究了两用户干扰信道的可达速率问题.将帕累托优化方法应用于耦合两用户干扰信道传输功率分配策略.结果表明:当系统处于帕累托最优时,使用最小发射功率可以达到最大信道速率.此外,每个信道的可达速率相等,且它仅与信道的参数有关.结论提供一个理论工具,应用该工具可以避免使用大量复杂的干扰抑制方法,达到获得最大信道速率的目的.From the viewpoint of information theory, achievable rates of two interference channels are studied in this thesis. Pareto optimality is applied to two coupling interference channels to allocate transmission power. The results show that when the system is in the Pareto optimality, using the minimum transmission power can reach the maximum channel rate. In addition, achievable rates are equal in each channel and it is only related to the channel parameters in the state of Pareto optimality. Furthermore, it provides a theoretical tool to avoid using too much complex interference mitigation method for achieving maximum rate of the channel.
