  • G3標準為窄頻電力線通訊實體層規範,其使用調變技術為OFDM系統,工作頻率範圍於低頻段,35.9kHz~90.6kHz。本論文遵循規格書建立G3系統實體層之傳送端與接收端軟體模擬平台,在考慮窄頻通道、背景雜訊與脈衝雜訊等影響下模擬驗證其系統性能,模擬結果顯示出,G3對於窄頻電力線通道環境,有不錯的效能。本論文也討論G3系統相關同步議題並比較G3與另一窄頻電力線通訊實體層規範PRIME之差異。最後本論文於Xilinx Virtex-4 FPGA驗證平台上實現G3系統。

    A new physical layer specification for narrow-band power-line communication, named G3, has recently been developed. The specification uses OFDM for data transmission and is intended to operate in the low-frequency band, from 35.9 kHz to 90.6 kHz.
    In this paper, we establish the software simulation platform at PHY layer of the transmitter and receiver of G3 specification, simultaneously considering the narrow -band PLC channel, narrowband background noise and impulsive noise effects. Simulation results show that G3 has a batter performance to conquer narrow-band PLC channel noise model.
    Subsequently, we discuss general OFDM synchronization problems and compare the performance of different narrowband power-line communication systems G3 and PRIME specification. Finally, we realize and verify the baseband transceiver of G3 Specification on Xilinx Virtex-4 FPGA development platform.
