Abstract

This paper considers the possibility and the details of implementing adaptive networks with visible light communication technology. Adaptive networks have various indoor and outdoor applications hence, their implementations with light waves face with different problems. Almost all free space optical (FSO)communication systems must deal with two channel deficiencies namely, optical noise and channel turbulence. Both channel noise and turbulence follow certain distributions that we explain in detail. In this paper, we analyze the effects of these disturbances on the estimation performance of incremental adaptive networks and present the results using various simulations. The results are presented by the means of mean square error values. Also, for Gaussian noise and Gamma-Gamma turbulence models we derived the theoretical mean square deviation (MSD)and excess mean square error (EMSE)values and compared them with the simulation outcomes.

基于γ - γ湍流的可见光通信信道自适应网络的实现

本文考虑了利用可见光通信技术实现自适应网络的可能性和细节。自适应网络具有多种室内和室外应用，因此，利用光波实现自适应网络面临着不同的问题。几乎所有的自由空间光通信系统都必须处理两个信道缺陷，即光噪声和信道湍流。通道噪声和湍流都遵循我们详细解释的某些分布。在本文中，我们分析了这些干扰对增量自适应网络估计性能的影响，并通过各种模拟给出了结果。结果用均方误差值的均值表示。此外，对于高斯噪声和Gamma-Gamma湍流模型，我们推导了理论均方偏差(MSD)和超额均方误差(EMSE)值，并将其与模拟结果进行了比较。
