Abstract :
The promotion and application of PLC technology has been restricted by the power line´s bad channel characteristics and noise distribution. In order to overcome these disadvantages and achieve more stable, secure and high speed level of communication, the writer designed a narrow-band high speed PLC communication platform based on G3-PLC. A FPGA was used to achieve the procedure of signal processing for transmitter and receiver. During which the OFDM technology, convolutional coding technology and Viterbi decoding were used. At last, the system is verified by a simulation and desired function is achieved.
