| 摘 要： | 自由空间光通信在各种应用中得到了广泛关注,但大气湍流效应导致系统链路性能恶化.假设大气湍流信道是无记忆平稳遍历并且为加性高斯白噪声(AWGN),自由空间光通信系统采用开关键控(OOK)强度调制直接检测(ID/DD),研究了gamma-gamma大气湍流信道下自由空间光通信的性能.利用MeijerG函数推导出了自由空间光...

| Abstract: | Free space optical(FSO) communication has attracted considerable attention recently for a variety of applications,but atmospheric turbulence can degrade the performance of FSO links.In this paper,the atmospheric turbulence channel was assumed to be memoryless,stationary and ergodic with additive white Gaussian noise(AWGN),the intensity modulation direct detection(ID/DD) with on-off keying(OOK) was used in FSO communication system.The performance of FSO communication systems was studied over gamma-gamma atmo... |
