Broadband communication on the automotive power network: Improving the OFDM waveform

In this paper, we propose a new communication strategy for transmitting high speed information over an electric propagation channel, type vehicle, based on the OFDM waveform (Orthogonal Frequency Division Multiplexing) The main objective is to highlight the effectiveness of the OFDM waveform for embedded PLC (Power Line Communication). Simulations are performed to validate the model transmission via the electric vehicle network. Two approaches face, one operator optimizing the channel coding and the other the number of used subcarriers. Results of the study of the bit error rates are presented, as well as the important parameters of the transmission chain to adjust depending on the channel and data to be transmitted. Suites to different simulation results, we can say that the OFDM waveform has certain robustness in the HomePlug standard for transmissions in the automotive network type direct channel. Thus, the optimization work on the duration of OFDM symbols and the size of the FFT is needed to counter the frame losses related to the use of an indirect channel and impulsive noise your abstract.
