摘要

本文基于${\bm{\kappa }}分布,为里氏非零孔径指向误差随机变量之和开发了一种创新的序列表示方法。- {\bm{\mu \ }}$ 分布,首次适用于多输入多输出(MIMO)传输。然后,利用这种新表示法,我们为具有广义指向误差和大气衰减的 MIMO 自由空间光学(FSO)通信的 Gamma-Gamma 随机变量之和引入了一种新的闭式概率密度函数(PDF)近似。Kolmogorov-Smirnov 统计测试证实了该近似值在各种信道条件下的准确性。通过使用 Meijer 的 G 函数推导出宏容量、中断概率和平均误码率 (BER) 的闭式表达式,强调了这一近似值的重要性。本文全面分析了利用等增益组合(EGC)分集技术的 MIMO FSO 系统在各种条件下的性能,如不同的发射器和接收器数量、湍流强度、非零孔径指向误差的影响以及路径衰减。研究结果表明,与其他分集技术(包括单输入单输出(SISO)和多输入多输出(MISO)系统)相比,使用具有更多发射器和接收器的多输入多输出(MIMO)技术可显著提高 FSO 通信的性能。对高信噪比情况下的遍历容量、中断概率和平均误码率性能的详细评估提供了更多启示。蒙特卡洛模拟结果证明了所提方法的准确性。

Novel Approximate Distribution of the Generalized Turbulence Channels for MIMO FSO Communications
In this article, we develop an innovative series representation for the sum of Rician non-zero boresight pointing error random variates based on the ${\bm{\kappa }} - {\bm{\mu \ }}$ distribution, which is suitable for multiple-input multiple-output (MIMO) transmission for the first time. Then, using this new representation, we introduce a novel closed-form probability density function (PDF) approximation for the sum of Gamma-Gamma random variates with generalized pointing errors and atmospheric attenuation of MIMO free-space optical (FSO) communications. Statistical Kolmogorov-Smirnov tests confirm the accuracy of this approximation over a wide range of channel conditions. The significance of this approximation is emphasized by deriving closed-form expressions for the ergodic capacity, outage probability, and average bit error rate (BER) using Meijer's G-function. This article provides a comprehensive analysis of the performance of MIMO FSO systems utilizing the equal gain combining (EGC) diversity technique under various conditions, such as different numbers of transmitter and receiver, turbulence intensities, the effects of non-zero boresight pointing errors, and path attenuation. The results show that using MIMO technology with more transmitters and receivers significantly improves the performance of FSO communication compared to other diversity techniques, including single input single output (SISO), and multiple input single output (MISO) systems. Detailed evaluations of the ergodic capacity, outage probability, and average BER performance at high signal-to-noise ratios provide additional insights. Monte-Carlo simulation results demonstrate the accuracy of the proposed approach.
