为了消除多用户全双工干扰信道中的自干扰和互干扰,将干扰对齐思想应用于全双工干扰信道中.根据多用户全双工模型的特性将其等效为单向信道模型,并给出了等效模型与原模型之间的信道矩阵对应关系;基于此等效模型和信道矩阵对应关系,应用迭代干扰对齐和最大信干噪比方法将其自干扰和互干扰消除;干扰泄漏功率的仿真结果验证了算法的有效性和正确性,系统容量和平均能量效率也较其他算法都有明显提高.
In order to eliminate self-interference and mutual interference in multi-user full-duplex interference channel, the idea of interference alignment is applied to full-duplex interference channel, which is equivalent to unidirectional channel model according to the characteristics of multi-user full-duplex model Based on the relationship between equivalent model and channel matrix, self-interference and mutual interference are eliminated by using iterative interference alignment and maximum SINR. The interference leakage The simulation results of power verify the validity and correctness of the algorithm, and the system capacity and average energy efficiency are obviously improved compared with other algorithms.
