摘要/Abstract

摘要：

摘要：针对传统光广义空间调制（OGSM）使用固定的光学天线组合集导致系统空间资源浪费和误码率性能受限的问题，提出一种基于低复杂度自适应光学天线组合集选择算法的改进型方案。首先，利用信道状态信息计算光学天线组合之间的欧氏距离矩阵。然后，基于欧氏距离等价原则和最大范数天线选择的思想，删除信道状态较差的光学天线组合，最终保留下的天线组合即当前状态下的最优光学天线组合集。所提算法避免了对所有候选天线组合的遍历，很大程度上降低了算法复杂度。仿真结果表明，所提方案的误码率性能在不同条件下均优于传统OGSM。

Abstract:

Aiming at the problems of space resource waste and error bit performance limitation caused by fixed optical antenna combination set used in traditional optical generalized spatial modulation (OGSM), an improved scheme based on low complexity adaptive optical antenna combination set selection algorithm was proposed.First, the Euclidean distance matrix between optical antenna combinations was calculated using channel state information.Then, based on the principle of Euclidean distance equivalence and the idea of maximum norm antenna selection, the optical antenna combination with poor channel state was deleted, and the final reserved optical antenna combination was the optimal optical antenna combination set in the current state.The traversal of all optical antenna combinations was avoided and the complexity of the algorithm was reduced to a large extent.The simulation results show that the BER performance of the improved OGSM scheme outperforms the conventional OGSM under different conditions.

Key words: free space optical communication, optical generalized spatial modulation, optical antenna combination set selection, Málaga turbulent channel, pointing error
