摘　　要：针对多小区边缘用户的干扰问题,设计了两时隙的传输协议,通过采用基于信漏噪比的预编码方案,推导获得所提传输协议下的预编码闭合表达式,并设计了基于非线性最小均方误差的自适应接收机。仿真结果表明所设计的传输协议与传统协议相比具有较大的和速率增益。A two-time-slot transmission protocol was designed according to the cell-edge users＇ interference problem. The precoder closed expressions under the proposed transmission protocol were derived based on the well-known precoder scheme of the signal-to-leakage-plus-noise ratio（SLNR）. Furthermore, an adaptive receiver was designed based on the non-linear minimum mean square error criterion. Simulation results demonstrated that the proposed transmission protocol has significant sum-rate gains compared with traditional system.
