Abstract
This paper presents the influence of line length,
number of branches (distributed and concentrated), and terminal
impedances on the performance of a low-voltage broadband
power-line communication channel. 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.
