Abstract
Currently, The new communication system was very important because of the increasing demand for Internet access. One of these alternatives is the PLC. But, Power Line is not suitable for communication. So, electromagnetic wave is generated from Power Line during flow of communication information. And the electromagnetic wave is interfered with Wireless Communication Service using the same frequency range. To eliminate this interference by used Notch tilter. Wavelet OFDM in another way, while one is used. In this paper, Wavelet OFDM CIC filter used in the CMFB structure by applying a further lowering the value of the side-lobe is proposed to improve performance.
