Experimental field trials of a utility AMR power line communication system analyzing channel effects and error correction methods

摘要

This paper analyses the effects of noise in a real Automated Meter Reading (AMR) environment where Power Line Communication (PLC) is used for meter reading. The aim is to give an analysis of periodic noise properties through its effect on a B-FSK based PLC system and to compare different error correction techniques under different constraints of attenuation and noise produced by the real loads installed in the network. Tests have been carried out using two different channel frequencies in the CENELEC A band taking into account frequency dependence of the line.
