Original Abstract

The article presents a design of the power line communication model. This model is composed of communication model, model of power line and noise model. The communication model is realized as the OFDM system, power line are modelled from transfer function of two-port network or from transfer function of multipath signal environment. Noise model are modelled as white noise, which gets a spectral colouring by a filter. On the resulting PLC communication model was shown comparison of different modulation technique and coding scheme. The different levels of mapping the carrier frequencies in OFDM were simulated on the proposed model from the viewpoint of comparing symbol error with signal to noise ratio and the interference effect to symbols rearrange in the constellation diagram were simulated as well.

Příspěvek se zabývá navrhem PLC komunikačního modelu. Tento model se skláda z komunikačního modelu, modelu vedení a modelu šumu a rušení. Komunikační model ja navržen jako OFDM model. Silnoproudé vedení je modelováno přenosovou funkcí dvojbranů nebo přenosovou funkcí prostředí s vícestným šířením. Model šum je modelován jako bílý šum se spektrálním zabarvením. Na výsledném PLC komunikačním modelu je ukázano porovnání různým modulačních technik a kódování.
