OFDMA Based Power Line Communication for Smart Grids

摘要

This paper investigates the design and simulation of Orthogonal Frequency Division Multiple Access (OFDMA) communication system using Narrowband-Power Line Communication (NB-PLC) for Smart Grids (SG) communication through extremely difficult channel environments such as multipath and noise. In OFDMA, sub-band carrier allocation is performed using contiguous, distributed and sorted sub-band carrier allocations and Bit Error Rate (BER) performance of this system is enhanced by these techniques, which are analyzed in this research. Simulation results indicates that sorted sub-band carrier allocation scheme gives better performance than contiguous sub-band carrier allocation scheme.%W artykule zbadano system komunikacyjny typu OFDMA wykorzystujący algorytm NB-PLC w zastosowaniu do sieci typu Smart Grid pracujący w trudnych warunkach zaszumienia. Do alokacji nośnej międzypasmowej wykorzystano Bit Error Rate BER algorytm.
