空间相关信道下均匀线阵和平面阵MIMO系统的有效检测

Efficient Detection in Uniform Linear and Planar Arrays MIMO Systems under Spatial Correlated Channels

João Lucas Negrão, Taufik Abrão

摘要:

在本文中,各种MIMO检测器的效率进行了分析,从高度相关的信道的角度来看,MIMO系统有缺乏的性能,除了在某些情况下增加的复杂性。考虑到这一困难但{有用}的场景,各种MIMO检测方案{关于}复杂度和误比特率(BER)性能进行了准确评估。具体地,连续干扰消除(SIC)、格基约简(LR)以及它们的组合与传统的线性MIMO检测技术相关联。{To为了证明有效性,已经考虑了宽范围的天线数量和调制格式,旨在根据其性能-复杂度权衡来验证这种MIMO检测技术的潜力。我们还研究了当发射和接收端都配备有均匀线阵(UWB)和均匀平面阵(UPA)天线配置时的相关效应。当两种天线阵列配置被部署{考虑}不同的天线数量和调制阶数时,特别是{在}近大规模多输入多输出条件下,仔细比较了不同检测器的性能。我们还讨论了阵列因子(AF)和两种{天线阵列}结构的BER性能之间的关系。

英文摘要:

In this paper, the efficiency of various MIMO detectors was analyzed from the perspective of highly correlated channels, where MIMO systems have a lack of performance, besides in some cases an increasing complexity. Considering this hard, but {a useful} scenario, various MIMO detection schemes {were accurately evaluated concerning} complexity and bit error rate (BER) performance. Specifically, successive interference cancellation (SIC), lattice reduction (LR) and the combination of them were associated with conventional linear MIMO detection techniques. {To demonstrate effectiveness}, a wide range of the number of antennas and modulation formats have been considered aiming to verify the potential of such MIMO detection techniques according to their performance-complexity trade-off. We have also studied the correlation effect when both transmit and receiver sides are equipped with uniform linear array (ULA) and uniform planar array (UPA) antenna configurations. The performance of different detectors is carefully compared when both antenna array configurations are deployed {considering} a different number of antennas and modulation order, especially {under} near-massive MIMO condition. We have also discussed the relationship between the array factor (AF) and the BER performance of both {antenna array} structures.
