摘要 文中根据能量效率准则分析了多用户MIMO下行联合发送(JT)技术发送端算法的性能。首先介绍了能量效率的概念及计算式;其次分析指出JT中采用的线性迫零(TxZF)算法的能量效率不高,有待改进;接着给出了具有高能量效率的非线性迫零算法(TxNZF);最后仿真计算了四种算法的能量效率及误码率,结果显示,TxNZF有着相对优越的性能。 In this paper, an energy efficient criterion for multi-user MIMO joint transmission （JT） schemes is presented. And then comparison of the above three linear signal processing algorithms based on energy efficiency criterion is described, and a nonlinear signal processing algorithm TxNZF which has high energy efficiency is proposed. Simulation results indicate that the TxNZF algorithm has superior performance as compared with linear algorithms in multi-user MIMO JT downlink.
