電力線通訊(Power line communication, PLC)是一種主要既有的有線通訊技術。電力線通訊利用現有的電力線做為資料傳輸之媒介。因此它具有許多優點，如低成本的佈線，無須建立新的實體聯結線，故使用上方便。本論文提出的高速電力線通訊晶片，可使用於一般家庭電力線上，採用HomePlug AV技術，其資料傳輸速度為142Mbps，採用正交分頻多工技術(Orthogonal Frequency Division Multiplexing, OFDM)來傳輸資料，每一段OFDM符號使用917個子載波。其中調變技術採用高傳輸效率的1024點的正交幅度調變(Quadrature Amplitude Modulation, QAM)，並採用3072點的快速傅立葉轉換(Fast Fourier Transform, FFT) 來實現訊號調變和解調。為保護資料傳輸時的安全性，使用高階加密標準(Advanced Encryption Standard, AES)來保護資料的安全。

Power Line Communications is one of the main existing wired communications technology. Power Line Communications uses the existing power lines as a data transmission medium. Therefore, it has many advantages, such as low-cost wire; there is no need to create a new power line. This paper uses the HomePlug AV technology standard to design a power line communication system. The data transfer speed of 142Mbps, using Orthogonal Frequency Division Multiplexing technology (OFDM) to transmit data. Long OFDM symbols with 917 usable carriers are used in conjunction with a guard interval. The modulation technique uses high transmission efficiency of the 1024-point Quadrature Amplitude Modulation and the use of the 3072-point Fast Fourier Transform signal modulation and demodulation. To protect the data transmission security, using the Advanced Encryption Standard (AES) to protect the security of information.
