A new structure for symmetric fir interpolator filter and its application in WCDMA
一种新的对称FIR内插滤波器结构及其在WCDMA中的应用

This paper proposes a new method to exploit the symmetric structure of prototype filters and provides a practical implementation structure which can be used in FPGAs, DSPs or commercial available digital filters. In the development of WCDMA mobile communication systems, this method is proposed to implement 64-order baseband shaping filter.
