一种基于MIMO-FSO的最大似然盲检测算法
A generalized maximum likelihood based blind detection for photon-counting MIMO free space optical systems
摘要
Abstract
This paper provides a new method of Mind detection based on Generalized Maximum Likelihood Sequence Detection(GMLSD) in Multiple-Input Multiple-Ouiput(MIMO) Free Space Optical (FSO) systems over weak, moderate and strong atmospheric turbulence channels. The. Detection scheme in this paper can perform sequence detection taking advantage of the spatial diversity in Equal Gain Cnmhining(EGC) MIMO systems without using any kind of channel knowledge. Furthermore, this paper develops a fast search algorithm which is suhoplimal and significantly reduces the computational complexity of sequence processing in receivers. Monte Carlo simulation results show the proposerd scheme obtains the spatial diversity in MIMO systems and reaches near optimal detection performance by using medium sequence lengths over different atmospheric turbulence fading models.关键词
