摘要

本文比较了在窄带电力线通信系统中广泛使用的FSK、SFSK和OFDM调制技术的性能。使用二进制和四元映射调制信号，然后暴露于实际测量的窄带PLC信道衰减和噪声。事实证明，4-SFSK具有最佳的误码率性能，在信噪比高于18 dB的信道效应下，误码率低于10−5，而OFDM-QPSK被限制在10−3。

SFSK versus OFDM Performances under the Narrowband PLC Channel Impairments

In this paper, we compare FSK, SFSK and OFDM modulation techniques performances, widely used for narrow band powerline communication systems. The signals are modulated using binary and quaternary mappings, then exposed to realistic measured narrowband PLC channel attenuation and noise. 4-SFSK proves to have the best BER performances, achieving BER lower than 10−5 under the channel effect for SNRs higher than 18 dB while OFDM-QPSK is limited to 10−3.
