基于能量效率的MIMO系统JT技术性能分析

Performance Analysis of MIMO JT Based on Energy Effciency

由于联合发送(JT)技术能大大的简化接收端的检测算法复杂度,目前引起许多文献对多用户MIMOJT技术的研究。本文首先介绍了多用户MIMOJT下行链路模型;其次引入了能量效率这一性能衡量准则,并对其进行修改,使其适用于JT技术;随后用能量效率及BER准则分析比较了JT发送端三种线性算法的性能。比较结果显示,TxZF算法对目前的JT技术更为适用。

For the JT scheme can simplify the complexity of detection algorithm at receiver, so Up to now many research works focus-es on JT scheme in multi-user MIMO systems. In this paper Firstly, we introduce a generic multi-user MIMO JT downlink trans-mission model. Then introduce energy efficiency as performance analysis criterion, and modify energy efficiency make it adapt for JT scheme. In what follows we do compare the three linear algorithms of JT based on energy efficient and BER criterion. Simulation re-sul...
