On Packet Detection Algorithm of G3-PLC Specification with Narrow-band Powerline Noise Interference

Abstract

Abstract: When exploiting orthogonal frequency division multiplexing technology based on G3 specification on smart grid,it’s necessary to solve the synchronization in harsh powerline environment for G3-PLC system.When there are background noise and impulsive interference in powerline channel,the classic delay-and-correlate packet detection algorithm has serious error.According to the characteristic of powerline noise,the classic packet detection algorithm is improved in order to increase the accuracy of detection.Through the evaluation of classic algorithm and new algorithm,the result shows new algorithm is more accurate than classic algorithm in the condition of powerline noise model.
