中文摘要：

研究了多小区网络通信系统的干扰消除技术，针对部分连通多输入多输出（MI—MO）干扰广播信道，提出了一种基于干扰对齐的低复杂度的线性收发机设计算法。该算法通过有效的对齐干扰，不仅能够完全消除小区间干扰，也能够完全消除小区内用户间干扰。同时为了达到每个用户d个系统自由度（DOF），给出了系统的基站数目、用户数目、基站和用户天线数目需要满足的条件，并且提出了一种启发式算法，用这种算法，在已知基站数目、用户数目、用户天线数目的情况下，能够得到系统基站所需的最少天线数目。仿真结果证明了上述算法的有效性。

英文摘要：

The interference elimination for a multi-cell communication system was studied, and a low-complexity linear transceiver design algorithm based on interference alignment for partially connected multiple input multiple output （MIMO） interfering broadcast channels was proposed. By aligning the interference effectively, the algorithm can eliminate both the inter-cell interference and the inter-user interference. Moreover, in order to achieve the degrees of freedom of d per user, the condition for the system＇ s base station （BS） number, user number, BS antenna number and user antenna number to meet was given, and a heuristic algorithm was put forward for obtaining the system＇ s minimum BS antenna number under the circumstances that the BS number, user number and user antenna number are known. The effectiveness of the proposed algorithms was verified by simulation .
