| 摘 要： | 在介绍无线光通信信道及系统模型的基础上，推导了无线光通信未编码系统和RS编码系统在已知信道边信息条件下的平均误码率，从接收光功率和对数振幅起伏方差方面对RS码编码系统和Turbo编码系统的性能进行比较.仿真结果表明，采用编码方案可以有效地改善大气湍流对通信链路性能的恶化，Turbo码编码方案比RS码编码方案能更好地抗大气湍流干扰.

| Abstract: | On the basis of introducing the channel and system model of wireless optical communication,average bit error rate of uncoded and RS coded system with channel side information were analyzed,and compared with Turbo coded system from the following two aspects:received optical power and Log-amplitude fluctuation variance.The results indicate that error performance can be improved effectively by coding; meanwhile,it can get better performance using Turbo code than using RS(Reed-Solomon) code to resist the atmosp... |
