Abstract

Massive MIMO (M-MIMO) devices are the key tool to meet the performance stards established for 5G-wireless communication. However, more Radio Frequency (RF) chains needed in base station (BS) with a huge count of transmitting antennas, involve expensive hardware and computing complexities. In order to decrease the RF chains needed in BS, this work intended to use the optimal transmit antenna selection (TAS) strategy. This strategy is gaining a lot of interest since the optimization algorithm aids in the ability to enhance the system performance considerably the efficiency and secrecy rate. This work proposes a novel Coati Adopted Pelican Optimization (CA-PO) for choosing the optimal TA by considering efficiency as well as secrecy rate. In addition, the CA-PO algorithm makes the decision on which antenna to be elected. At last, the supremacy of CA-PO-based TAS is proven from the analysis regarding secrecy rate and EE analysis. Accordingly, the proposed CA-PO method for MF for set up 2 has attained a higher EE of 0.976; whereas, the DMOA, COA, MRFO, POA and BEA techniques have got a relatively lower EE of 0.968.

利用元启发式辅助模型在 M-MIMO 系统中选择发射天线

大规模多输入多输出（M-MIMO）设备是满足 5G 无线通信性能标准的关键工具。然而，基站（BS）需要更多的射频（RF）链，发射天线数量庞大，涉及昂贵的硬件和复杂的计算。为了减少基站所需的射频链，这项工作打算采用最佳发射天线选择（TAS）策略。由于优化算法能显著提高系统性能的效率和保密率，因此该策略受到广泛关注。本研究提出了一种新颖的鹈鹕优化算法（Coati Adopted Pelican Optimization，CA-PO），通过考虑效率和保密率来选择最佳发射天线。此外，CA-PO 算法还能决定选择哪种天线。最后，通过对保密率和 EE 的分析，证明了基于 CA-PO 的 TAS 的优越性。因此，针对设置 2 的中频提出的 CA-PO 方法获得了 0.976 的较高 EE；而 DMOA、COA、MRFO、POA 和 BEA 技术获得了 0.968 的较低 EE。
