    摘要:

    针对多用户多输入多输出(MIMO)干扰网络条件下,干扰对齐算法性能受限的问题,提出一种多用户MIMO网络下基于分簇的非迭代干扰对齐算法。通过一种分层的干扰处理设计,首先在上层依据干信链路耗损比,将来自不同发送端的干扰分为簇内有效干扰和簇间无效干扰;然后在下层利用联合最大化信漏噪比(SLNR)算法与迫零(ZF)算法消除干扰,提升了算法的适用性。仿真结果表明,当用户数量较多时,所提算法与现有算法相比,在高信噪比(SNR)条件下具有更高的系统容量与更低的系统复杂度。

    Abstract:

    Aiming at the problem of limited performance of the Interference Alignment(IA) algorithm in the multiuser Multiple-Input Multiple-Output(MIMO) interference network, a non-iterative interference alignment algorithm based on clustered is proposed. The algorithm is based on a hierarchical interference processing design. First, the interference from different transmitters is divided into intra-cluster effective interference and inter-cluster invalid interference in the upper layer by interference to signal transmission path ratio. Then, the joint maximum-Signal to Leakage plus Noise Ratio(SLNR) algorithm and the Zero Forcing(ZF) algorithm are utilized in the lower layer to eliminate the interference and finally improve the applicability of the algorithm. Simulation results show that the proposed algorithm has higher system capacity and lower system complexity at high Signal-to-Noise Ratio(SNR) than the existing algorithms when the number of users is large.
