For analyses, the systems chosen are typical low-voltage power-line networks found in Tanzania. The parameters varied were the network’s load impedances, direct line length (from transmitter to receiver), branched line lengths, and number of branches. From the frequency responses of the transfer functions (ratio of the received and transmitted signal), it is seen that the position of notches and peaks in the amplitude responses are affected by the aforementioned network parameters and topology. As a result, the time-domain responses are attenuated and distorted. Time-domain responses of power-line channels under various conditions are also investigated for a given pulse input at the transmitter. The observations presented in this paper could be useful for suitable power-line communication system design.enBroadband power-line communication,channel model,concatenated coding,impulsive noise,interleaving,multipath channel,punctured convolutional codes,Reed Solomon codes,transfer functionJournal Article, Peer Reviewed
