Design and Implementation of OFDM Modem for Low Voltage Narrowband Powerline Communication

Article Preview

Abstract:

Narrowband powerline communication has the great potential market application like Auto-Meter-Reading (AMR). This paper focuses on the design and implementation of narrowband powerline communication module with the OFDM technology. Firstly, it introduces the OFDM solution for low voltage powerline communication module design, then it describes the implementation of the sync module, Viterbi code translation module and FFT module based on FPGA platform in details. Finally, it provides the actual test results for the communication module. It shows, the communication data rate of the narrowband powerline communication is greatly improved with OFDM technology.
