摘要:
由于毫米波多用户大规模MIMO系统采用全数字预编码时,面临硬件复杂度过高、成本和能耗较高的问题,模数混合预编码是一种有效的解决方案.文章提出基于信漏噪声比(SLNR)的混合预编码器算法用于多用户毫米波大规模MIMO系统,该算法将噪声计算在内可以阻止噪声的放大并能有效抑制同信道干扰.与迫零算法相比,该算法对发送端和接收端天线数没有限制.仿真结果表明,在有效减少系统所需射频链路数量的基础上,所提混合预编码方案能够接近传统全数字预编码方案的性能.
Abstract:
For a massive multiple-input multiple-output(MIMO)systems,the hybrid precoding scheme which restricts the number of RF chains to far less than the number of antenna elements has attracted the attentions from both academy and industry.In this paper,we considered the downlink communication of a mmWave multiuser massive MIMO system and proposed a hybrid precoding algorithm based on maximum signal-to-leakage-and-noise ratio.The algorithm can avoid noise amplification and repress the co-channel interference.Compared with the zero forcing algorithm,the proposed algorithm has no limitation on the number of transmitter and receiver antennas.Simulation results showed that the proposed hybrid precoding scheme can approach the performance of the traditional full digital precoding scheme.
