A Sort of Raise Cosine Filter Design
Xinxing Jing · Modern Electronics Technique · 2006
The implementation of a high performance pulse shape digital filter used in PHS baseband system is proposed.Two types of coefficients transforms are compared,The minimal number of nonzero digitals called Canonic Sign Digital(CSD) and common substructure sharing mode are used to improve performance of raise cosine shape filter.The function simulation,synthesis and postsynthesis simulation are achieved and the ASIC design is under the process of SMIC 0.18 μm.
