基于幅值密度特征的调制格式识别方法
Modulation format recognition method based on amplitude density characteristics
摘要
Abstract
To enhance the performance of future elastic optical networks,a modulation format recognition method based on am-plitude density features is proposed.This method uses amplitude density features as input to an improved MobileNetV2 model to identify modulation formats and introduces a normalized attention mechanism(NAM)for accurate identification of transmission signal modulation formats.The feasibility of this approach is verified in 28 GBaud quadrature phase shift keying(QPSK),8-level quadrature amplitude modulation(8QAM),16QAM,32QAM,64QAM,and 128QAM transmission systems.The experimental results show that the minimum optical signal-to-noise ratio(OSNR)required for achieving 100％recognition accuracy for each modulation format is below its corresponding 20％forward error correction(FEC)threshold.Furthermore,within a broad OSNR range,a recognition accuracy of 99.62％is achieved.In optical networks with residual dispersion,this approach still maintains high recognition performance.关键词
