Abstract :
In this paper, the process in high-speed powerline communications are presented and computationally implemented. A simulation system with transmitter, channel and receiver is generated. The data transmission is simulated and the signal noise ratio (SNR) are collected. By analyzing the noise morphology in the detection process, propositions of changes in the modulation structure are done in order to take an adaptive system on the channel characteristics.
