Modulation classification based on polar coordinates of received signal point

CHENG Han-wen1,2,WU Le-nan1(1.Department of Radio Engineering,Southeast University,Nanjing 210096,China;2.Air defense forces command academy,Zhengzhou 450052,China)  
This paper proposes a recognition algorithm for digital modulated signals.This scheme picks up polar coordinates of received signal point as characteristic.Based on comparable measure between samples and kernels to cluster observation point of received signals,it utilizes dynamic clustering for constellation classification of different modulated signals and completes the modulation recognition.Computer simulations show its effectiveness on mitigating phase estimation error.
