THE INFLUENCE OF BRANCHES IN THE PERFORMANCE OF POWER-LINE COMMUNICATION SYSTEMS THAT USE MC-CDMA WITH REED SOLOMON CODING

Abstract

Power-line network is proposed as an infrastructure for Information and Communications Technologies (ICTs)services provision. However, there are a number of factors that contribute greatly to power-line communicationperformance degradation. These include number of branches that can be added or removed from the power-line network, lengths of the branch lines, loading etc. It has been pointed out that the number of branchesis one of the factors that affects power-line performance to a certain extent. In this paper the influence ofnumber of branches on the performance of Broadband Power-line communication (BPLC) that uses MC-CDMA modulation scheme with Reed Solomon coding is investigated. It is shown that with substantial numberof branches at a particular node in power-line a performance BER of 10-6 at SNR of about 25dB with channelcapacity of 300Mb/s can be attained
