摘要

为了控制自由空间光通信系统的成本、体积和功耗

便于系统的维护与运行

针对现有的自由空间光通信系统一般采用强度调制/直接解调的方式

提出了一种新型的基于K平均算法的接收机结构

并从执行复杂度、鲁棒性和差错性能等方面与经典算法进行比较分析。结果显示

当数据块长度达到1 000时

所提算法性能可以逼近理想接收机性能。

Abstract

To reduce the cost

size and power consumption of the Free-Space Optical（FSO）communications system for easy operation and maintenance

most common FSO systems use Intensity Modulation and Direct Detection（IM/DD）.This paper proposes a signal detection method based on the K- mean algorithm

and compares it with classical algorithms in terms of implementation complexity

robustness and error performance.The results show that when the data block is longer than 1 000

the performance of the proposed method can approach that of the ideal receiver.
