摘要

在本文中，我们分析了多输入多输出(MIMO)空间移位键控(SSK)调制在新提出的具有指向误差的大气湍流模型Fisher-Snedecor (F)分布中的性能。针对有指向误差的F分布，推导了信道增益差矩生成函数，得到了平均误码率。结果表明，分集增益与大气湍流和指向误差无关，且随接收机数量的变化而变化。分析了接收机数量的增加会提高系统的ABER性能。此外，我们比较了SSK调制与PPM和PAM调制方案的F分布，并比较了SSK调制方案的F分布与Gamma-Gamma分布。

Analysis of Space Shift Keying Modulation over F Turbulence Channel Model in FSO Communication

In this paper, we have analyzed the performance of multiple-input multiple-output (MIMO) Space Shift Keying (SSK) modulation over the newly proposed atmosphere turbulence model Fisher-Snedecor (F) distribution with pointing error. The moment generating function (MGF) of channel gain difference is derived for F distribution with pointing error to obtain the average bit error rate (ABER). Results show that diversity gain remains constant irrespective of atmospheric turbulence (AT) and pointing errors, and it varies when we vary the number of receivers. It is also analyzed that when we increase the number of receivers, the system performance improves the ABER. Moreover, we compare the SSK modulation with PPM and PAM modulation schemes for F distribution and we also compare the F distribution with Gamma-Gamma distribution for SSK modulation scheme.
