摘要：
When using power line communications (PLC) modems for Smart Grids (SG), achieving fast and reliable data transmission is one of the key issues. This paper investigate a soft Viterbi decoder to reduce errors effects of noises and attenuations in Spread Frequency Shift Keying (S-FSK) communication scheme. Through numerical simulations, the improvements of the proposed Viterbi decoder are shown in terms of BER performance. Furthermore, practical realization on low-cost embedded processor is discussed. The whole design of a narrowband S-FSK based PLC modem has been implemented and optimization for real time processing.
