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.
In the view of information theory, this paper studies the problem of two-user interfering channel’s reachable rate. Pareto optimization method is applied to transmit power allocation strategy of two-user interfering channel transmission. The results show that when the system is Pareto-optimal, Power can reach the maximum channel rate.In addition, the achievable rate of each channel is equal and it is only related to the parameters of the channel.Conclusions provide a theoretical tool, which can avoid the use of a large number of complex interference suppression methods to achieve the maximum channel The purpose of the rate.
