Abstract

Multi-carrier modulation based on the wavelet is applied on power line communication to obtain high communication performance in this paper. The noise and attenuation model of power line channel for the data communication are established at first, on which the multi-carrier modulation method based on complex wavelet packet is adopted. Furthermore, the wavelet-based functions with various support lengths are selected in simulation to compare with the Fourier-based multi-carrier communication. Finally, the effects by selecting various wavelet-based functions are analyzed and compared. Compared through simulation results, the technique of wavelet-based multi-carrier modulation is more suitable than Fourier-based multi-carrier communication. Meanwhile, selecting the suitable wavelet-based functions with various support lengths can affect the performance of communication, especially the Bit Error Rate (BER).
