The universality of the power line network
presents the power line communication (PLC) as the
choice technology for this generation. Its inherent
challenges are a major drawback on its acceptability
and deployment. These challenges are of noise,
attenuation and multipath. In this paper, power line
cooperative communication (PLCC) system was
presented. The two cooperative transmission protocols
deployed, amplify-and-forward and decode-andforward,
were preceded by a noise mitigation system.
This noise system improves the bit error rate
performance of the system. The reliability of the
PLCC system was investigated, using channel
capacity, symbol error rate and outrage probability as
performance metrics. The channel capacity of both
cooperative links yields enormous increase as
compared to the direct (conventional) link. Systems
symbol error rate was drastically reduced and
probability of outages forced down on the links with
cooperation, thus achieving the systems reliability. In
the investigation, the decode-and-forward cooperation
protocol out performs the amplify-and-forward, while
the noise mitigation system, brought the SER and
outage probability of both protocols close. The best
performance in cooperation is a relay location midway
between source and destination nodes. Thus,
cooperative relaying is seen to have achieved
reliability of the PLC in broadband transmission.

Amplify-and-forward, channel capacity,
decode-and-forward, symbol error rate, and outage
probability
In this paper, a technique deployed to achieve
reliability ii the power line communication (PLC)
system is presented. The technique is a, modem
(relay) cooperating with the source modem for signal
transmission to the destination. The key contribution
is in the system reliability achieved, for which
system’s channel capacity, outage probability and
symbol error rate were parameters investigated. Two
cooperative channels, amplify-and-forward and the
decode-and-forward, along with the direct channel
(without cooperation), were examined for those
parameters mentioned. The cooperative links were
seen to attain outstanding reliability over the direct
link. The noise mitigation system incorporated
contributed enormously to the drastic reduction in the
systems symbol error rate and outage probabilities of
both cooperative links, achieving performances that
are close. Deployment of further cooperative activities
for improvement of the systems reliability can be
investigated. The effects of these activities on the
channel capacity and other performance metrics will
be studied.
