Abstract
By the spread of Internet, home networking attracts much attention of people. The indoor power lines are potentially wide-spread, convenient and inexpensive “no new wire” candidate medium for data transmission. However, there are many technical problems to realize power line communication system with high rate and high reliability. After all, power lines are not devised for communication.
In the thesis, we study the characteristics of power line channel like multipath effect and various types of noise. We choose four multipath channel models and take Middleton’s Class A noise as noise model in our simulation. And based on some HomePlug 1.0 Specification, we compare the performance of several effective coding on power line channel. We find that turbo code perform poorly as expected in some kind of channels, but we could always get better performance by using trellis codes with larger free distances in all channels.
