| Summary: | 碩士 === 國立成功大學 === 電腦與通信工程研究所 === 104 === This thesis follows the G3-PLC standard to implement a narrow-band power line communication (PLC) system. The system adopts orthogonal frequency division multiplexing (OFDM) and differential phase shift keying (DPSK) modulation as the main communication techniques. This work contains system simulations and system implementation. In the system simulations, a complete power-line channel model is involved to verify the feasibility and performance of the designed transmission/receiving algorithms. According to the simulation results, we propose some methods to reduce the implementation complexity. In the system implementation, we first measured the power-line channel at the lab. According to the measurement, we shift the target PLC system to the proper transmission band. Then, this work designed and implemented the analog front end circuits and realized a practical narrow-band PLC transceiver.
