Abstract :
This paper presents new solutions for powerline communication under strong noise background. A new method of auto-search centre frequency of SSC signals has been proposed for various conditions and the general electrical engineering applications. In order to optimize data transmission, the centre frequency can be changed suitably according to the minimum power spectrum of signals. The method uses SSC technology directly, only changes its centre frequency according to the practical status, and avoids complex encode and decode procedure. Experimental results indicate that the transmission successful rate has been improved remarkably and the scheme has high performance under strong noise background
