摘要
对现有干扰系统中非合作博弈功率控制问题进行了总结和分析。主要分析了四种效用函数,并研究了相应的应用策略。从中可以看出,基于互信息量的效用函数运算较复杂,目标容量确定下的效用函数与目标信干噪比确定下的效用函数在性能不影响的情况下,计算复杂度大大降低。基于效率的效用函数能有效抑制各用户对发射功率的盲目追求,提高了用户单位功率下的性能,即提高了效率。
In the paper,it summarizes and analyzes the question of power control based on non-cooperative game theory in the MIMO interference systems.Mainly,it is divided into four parts.From this paper,the first one is complicated computation.The following two can not only guarantee the good performance,but also reduce the complexity.Moreover,the last one can restrain the transmit power of every user,so as to improve the performance of unit power,namely to improve the efficiency.
