Abstract

This paper investigates the performance of coherent-state quantum optical wireless communication systems operating over atmospheric turbulence channels with pointing errors (PEs). The average error probability (AEP) and average achievable rate (AAR) are analyzed for on–off keying (OOK) and binary phase-shift keying (BPSK) signaling under photon-counting (PC), homodyne, and optimal Helstrom detection. The proposed framework jointly incorporates deterministic path loss, atmospheric turbulence, and PEs, and accommodates multiple statistical channel models, including Gamma-Gamma (GG), doubly inverted Gamma-Gamma (IGGG), and Fisher-Snedecor

$F$

distributions, within a unified analytical formulation. Closed-form expressions for AEP and AAR are derived via direct probability density function (PDF)-based integration of the conditional error probability, along with high-photon-number asymptotic approximations that provide insight into performance scaling behavior. Numerical results validate the analytical expressions and demonstrate the impact of PEs on system performance. The analysis further enables systematic comparison between classical and optimal quantum detection schemes and quantifies the achievable performance gains under different channel conditions. These results provide useful design insights for modulation and receiver selection in turbulent free-space optical (FSO) communication systems.

具有指向误差的湍流信道上相干态量子无线通信性能分析

研究了在具有指向误差的大气湍流信道上工作的相干态量子无线通信系统的性能。分析了开关键控（OOK）和二相移键控（BPSK）信号在光子计数（PC）、纯差（homodyne）和最优Helstrom检测下的平均误差概率（AEP）和平均可达率（AAR）。提出的框架将确定性路径损失、大气湍流和pe结合在一起，并在统一的分析公式中容纳多种统计信道模型，包括Gamma-Gamma （GG）、双倒Gamma-Gamma （IGGG）和Fisher-Snedecor $F$分布。AEP和AAR的封闭表达式是通过基于条件误差概率的直接概率密度函数（PDF）的积分，以及高光子数渐近近似推导出来的，该近似提供了对性能缩放行为的洞察。数值结果验证了解析表达式的正确性，并证明了pe对系统性能的影响。该分析进一步使经典和最优量子检测方案之间的系统比较，并量化在不同信道条件下可实现的性能增益。这些结果为湍流自由空间光学（FSO）通信系统的调制和接收机选择提供了有用的设计见解。
