面向自由空间光通信波前校正的改进模拟退火算法
Improved simulated annealing algorithm for wavefront correction in free-space optical communication
摘要
Abstract
To compensate for atmospheric turbulence-induced wavefront distortion in coherent free-space op-tical communication,we develop an adaptive optical system based on the improved simulated annealing al-gorithm.The system seeks to optimize mixing efficiency and reduce the bit error rate,ultimately enhancing overall system performance.First,we describe the structure of a coherent optical communication system without a wavefront adaptive optics component,focusing on key parameters such as mixing efficiency and bit error rate.Next,the paper implements a detailed explanation of the working principles of the improved simulated annealing algorithm and its application in adaptive optical systems.To validate the proposed al-gorithm's effectiveness,numerical simulations are performed and compared against traditional algorithms.Fi-nally,real-world data is collected from an experimental platform to further assess the algorithm's perform-ance.Experimental results demonstrate that,in comparison to the standard simulated annealing algorithm,the improved simulated annealing algorithm reduces the iteration count by 50％,decreases the bit error rate to 10-9,and increases the mixing efficiency to 0.9.Overall,the improved simulated annealing algorithm effect-ively reduces the iteration count in traditional adaptive optical systems,enhances wavefront correction accur-acy,and satisfies communication system requirements.关键词
