Modulation Classification Using Received Signal’s Amplitude Distribution for Coherent Receivers
IEEE Photonics Technology Letters(2017)
摘要
In this letter, we propose a modulation classification algorithm, which is based on the received signal's amplitude for coherent optical receivers. The proposed algorithm classifies the modulation format from several possible candidates by differentiating the cumulative distribution function (cdf) curves of their normalized amplitudes. The candidate with the most similar cdf to the received signal...
