摘要

研究了一种基于差分相移键控子载波强度调制(DPSK-SIM)的自由空间光学(FSO)通信系统在具有指向误差的强大气湍流信道上的性能。推导了平均误码率、信道容量和中断概率的新的封闭解析表达式。用二维和三维图形分析了dsk - sim调制技术的平均误码率、信道容量和中断概率的仿真结果。

Performance analysis of DPSK-SIM based FSO system over strong atmospheric turbulence channel

This paper investigates the performance of a differential phase shift keying subcarrier intensity modulation (DPSK-SIM) based free space optical (FSO) communication system over strong atmospheric turbulence channel with pointing errors. Novel closed-form analytical expressions are derived for average bit error rate (BER), channel capacity and outage probability. The simulated results for average BER, channel capacity and outage probability of DPSK-SIM modulation technique is analyzed with 2D and 3D plots.
