摘要

毫米波(mmWave)是未来高速移动通信的一个有吸引力的候选技术。然而,由于毫米波的传播特性,波束对齐成为服务高速移动用户的关键挑战。本文中,我们开发了一种联合波束与信道跟踪算法,利用二维(2D)相控天线阵列从水平与垂直方向跟踪波束。获得了一般的最优试探波束成形参数序列,以在天线数趋于无穷时渐近达到联合波束与信道跟踪的最小 Cramer-Rao 下界(CRLB)。该序列被证明在不同条件下(如信道系数、路径方向和天线阵列尺寸)渐近最优。我们证明了所提算法在静态场景下收敛到最小 CRLB。仿真结果表明,我们的算法在跟踪精度和速度带宽上优于几种现有算法。

备注

arXiv admin note: substantial text overlap with arXiv:1804.06258. Because the first author did not know the rule of arXiv that all submitted papers can not be removed completed, the same paper was submitted twice with different titles. It has caused confusion to readers. Hence, we remove this paper and reverse arXiv:1804.06258
