Abstract
Broadband Power Line Communications (PLC)
technology allows the usage of electrical power supply networks
for communications purposes, such as audio/video streaming and
broadband internet access. The powerline has an inherent
characteristic that is the cyclic variation of channel and noise with
the phase of the AC line cycle. To achieve either high throughput
or high robustness, we apply dynamic channel adaptation scheme
that exploits the cyclic variation of powerline characteristics. In
this paper, we introduce an expedient, dynamic channel
adaptation which is robust against the short-time variation of the
AC synchronized powerline channel and noise. We analyze the
performance enhancement for the measured powerline channel
and noise when the proposed adaptation scheme is applied to the
Korean standard on high speed powerline communications.This work is supported by Brain Korea 21 project
