G.hn 為正發展的通用家庭連網(Home Network, HN)協定，此協定將同時支援、整合室內電話線、同軸電纜及電力線等傳輸通道環境，且傳送速率可達每秒十億位元(1Gbps)，預期將成為新世代家庭網路有線連網的基礎。而G.hn 協定的傳輸通訊標準為國際電信聯盟(International Telecommunication Union, ITU)正進行制定的G.9960標準。
本論文針對目前G.9960標準的實體層規範，尤其與電力線傳輸相關設計，進行深入研究，瞭解此規範細節，並研究設計其傳送及接收端訊號處理演算法，包含低密度同位元檢測碼 (LDPC code) 編解碼、初步同步中對於時間偏移 (Timing Offset) 與取樣頻率誤差 (Sampling Clock Offset) 的偵測與補償，和針對電力線通道模型所做的通道偵測與等化器設計等。最後以電腦軟體程式C及Matlab建立G.hn規格實體層標準G.9960的模擬平台，進行全系統測試及性能驗證。

G.hn is a promising Home Networking (HN) standard which is being under developing. This standard aims to support the communications over premises wiring including indoor telephone wiring, coaxial cables, and power line wiring, and combinations of these. And its transmission-rate is up to 1 gigabit per second (1 Gbps). G.hn system is expected to become the new generation of home networking wired foundation. The communication specifications of G.hn will follow Recommendation G.9960 Foundation which is being formulated by ITU (International Telecommunication Union).
The work of this thesis focuses on the study of physical layer specifications of G.hn standard (i.e., G.9960 spec.), especially on the system design related to the power line communications. In this project, we conduct the whole system design which includes the encoding/decoding schemes of LDPC (Low Density Parity Check) code, the detection of signal arrival, the synchronization of initial symbol timing, the impact-evaluation of sampling clock offset, and the channel detection and equalization for power-line channels. Finally, a software simulation platform based on Matlab and C codes has been developed to evaluate the system-wide performance.
