中文摘要：
针对每个基站有多个发射天线、每个用户有多个接收天线的多小区多用户多输入多输出（MIMO）下行网络系统,为抑制小区外干扰和小区内干扰对小区边缘用户的影响,分别基于块对角化算法和最小均方误差算法提出了两种非迭代干扰抑制方法,并分析了发射天线数和接收天线数受用户数及小区个数的影响.仿真结果显示,这两种方法均能很好地提高小区边缘用户的频谱效率.
英文摘要：
In order to mitigate the out-of-cell and the intra-cell interferences in the cell-edge users in downlink multi-cell multi-user MIMO（Multiple-Input Multiple-Output） systems where each base station has multiple transmitting antennas and each mobile user has multiple receiving antennas,two interference suppression techniques respectively based on the block diagonalization and the minimum mean-squared error algorithms are proposed,and the numbers of transmitting antennas and receiving antennas affected by user number and cell number are analyzed.Simulated results indicate that the two techniques both greatly improve the spectral efficiency of cell-edge users.
