We mainly compared the performance of Fast Fourier Transform(FFT)Orthogonal Frequency Division Multiplexing(OFDM)and Discrete Wavelet Transform(DWT)OFDM in Power Line Communication(PLC).We first shown the PLC channel model.Then the Bit Error Rate(BER)and Peak-to-Average Power Ratio(PAPR)performances of DWT-OFDM and FFT-OFDM are analyzed with the interference of Additive White Gaussian Noise(AWGN)and Carrier Frequency Offset(CFO).Throughout the simulation
DWT-OFDM is more appropriate to power line communications in the PLC system
which will make significant influence on the PLC in the future.
