An Information Theoretic Analysis on Indoor PLC Channel Characterizations

Power-Line is recently considered as a future medium for the high rate transmissions. But the development of Power Line Communications (PLC) highly depends on the knowledge of (he channel characterizations. For this reason, a large number of attentions have been payed on the PLC channel analysis using the measurements. This paper highlights an information theoretic analysis for indoor PLC channel environment investigation, wherein, the estimated channel entropy and the power delay spectrum are expected to give us much useful information to describe the indoor PLC channels. Moreover, the study on the PLC channel degree of freedom distribution and the discussion of choosing whether wide-band or multi-band are included in this paper.
