A channel filter has been designed for Digital Down Converter (DDC) that meets the standard of WiMAX in wireless communication. WiMAX is a technology emerging in the wireless communication system, in order to enhance the broadband wireless internet access. Digital Up Converter (DUC) and Digital Down Converter (DDC) are integral part of WiMAX system that results in efficient low cost WiMAX system. In order to fulfill the spectral requirement of bandwidth reduction, effective spectral leakage and eliminating interference from adjacent channels, in WiMAX system, DDC and DUC utilizes a channel filter for pulse shaping.
