Comparison of FMT and OFDM systems in power line channels
FMT与OFDM系统在电力线信道下的性能研究

Performance of filtered multitone modulation (FMT) system and orthogonal frequency division multiplexing (OFDM) system in the power line channel is compared in order to find a new modulation and demodulation technique suitable for power line communications (PLC) systems. Simulation results show that under the defined channel model FMT system outperforms OFDM system in the presence of impulses in the frequency domain and narrowband interference, but OFDM system performs better in the presence of impulses in the time domain.
