对OFDMA系统中的干扰协调进行了研究,提出了一种基于部分可观察马尔可夫决策过程理论的动态干扰协调算法。该算法结合干扰的统计模型和信道的信干噪比对边缘用户进行信道分配。仿真结果表明,该算法能够有效地使边缘用户避开邻小区干扰,而且不需要小区间交互,节省了系统开销。另外,利用粒子滤波法建立了SINR和干扰的似然关系,不需要系统额外对干扰进行测量。
The inter-cell interference coordination(ICIC)of OFDMA system was studied,and a dynamic ICIC algorithm based on the theory of partially observable Markov decision process(POMDP)was proposed.The statistic model of interference and SINR of channel was combined to allocate channels for cell-edge user in this algorithm.Simulation results show that the proposed scheme can efficiently avoid interference for the cell-edge user.Since this algorithm avoids the coordination between cells,the system overhead is saved.Furthermore,a likelihood relation between SINR and interference was established by using particle filter,so there was no necessary for system to measure the interference.
