ㄧ般居家住宅的低壓電力線網路是非常便利以及價錢低廉的傳輸媒介，然而，原本電力線網路並非為通訊傳輸所設計，所以要在電力線網路上傳輸高速的的資料可能會遭受很多問題。
本論文著重在研究電力線通道的特性包括各種不同的雜訊，變化不定的阻抗 和衰減，並且建立了一個電力線通道模型，和各種不同的雜訊模型以及非理想的特性，以便於模擬。此外，依照HomePlug 1.0 Specification 所定義的實體層建立一個高速的基頻通訊系統，並且利用ㄧ個簡單的資料及功率分配方法來增加電力線通訊的通道容量以及利用錯誤控制碼來降低干擾所造成的影響。

The in-building low-voltage power-line networks are a convenient and low cost medium for digital communications. However, since power-line networks are not originally designed for communication, it may suffer from a lot of channel degradation and interference to transmit high-speed signals on them.
In this thesis, we have studied the characteristics of power-line channel which include the various types of noises, the time-varying impedance and the attenuation. We have built a power-line channel model for simulations. We design a FEC coded system based on the HomePlug 1.0 Specification to reduce the effects of the narrowband interferences presented in the power-line networks. We propose a bit and power allocation scheme with low complexity to enhance the system capacity of the power-line communication at a target bit error rate.
