In this paper a pulse shaping filter called channel filter is designed for digital up converter (DUC) block in WIMAX IEEE 802.6e standard. The requirement of the pulse shaping filter arises from two reasons one being generation of band limited channels and another reduction in interference. The pulse shaping filter used here is a root raised cosine filter (RRC) as it fulfils the conflicting requirement of communication systems. Design simulation and analysis is done using MATLAB with two windows namely Kaiser and Bartlett. A comparison is performed between their magnitude responses and implementation cost. From comparative analysis of results it can be observed that usage of Bartlett window with RRC technique has resulted in reduced cost due to less number of multipliers and adders requirements as compared to Kaiser Window.
